8 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
9 files are lib/silcutil/silcstrutil.[ch].
11 * Defined that the security property fields in SKE SHOULD be
12 UTF-8 encoded, defined that version string MUST be US-ASCII
13 encoded, defined that passphrases sent in connection
14 authentication protocol MUST be UTF-8 encoded. Implemented
15 these to the client and server. Defined also that other
16 passphrases sent in the protocol MUST be UTF-8 encoded.
17 Affected files are lib/silcske/silcske.c,
18 lib/silcclient/protocol.c, silcd/protocol.c,
19 silcd/serverconfig.c, and lib/silccore/silcauth.c.
21 * Changed the silc_client_close_connection interface to not
22 need the SilcSocketConnection which should not be visible
23 to application. Affected files are lib/silcclient/client.c
24 and lib/silcclient/silcclient.h.
26 * Rewrote the text for Private Message Key Payload in the
27 protocol specification. Protocol TODO #11.
29 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Upgraded the protocol version to 1.1, updated protocol specs
34 * Added the nickname as new argument to NICK_CHANGE notify and
35 added it to protocol specs and implemented it to client and
36 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
37 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
38 lib/silcclient/client_notify.c.
40 * Added the killer's client ID to the KILLED notify and added
41 it to protocol specs and implemented it to client and server.
42 Protocol TODO #13. Affected files are silcd/command.c,
43 silcd/packet_receive.c, packet_send.[ch],
44 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
45 The killer's client entry is now returned to application in
46 the `notify' client operation.
48 * Fixed the Max Argument fields that had too large value set
49 in the protocol specs. Protocol TODO #14.
51 * Added the LEAVE command reply to return the ID of parted
52 channel. Updated protocol specs and implemented it to the
53 client and server. Protocol TODO #15. Affected files are
54 silcd/command.c, lib/silcclient/command_reply.c. The channel
55 entry is now returned to application in the `command_reply'
58 * Rewrote the version SKE version checking in client libary
59 and in server to use the silc_parse_version_string. Affected
60 files are lib/silcclient/protocol.c, silcd/protocol.c.
62 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
63 commands that was missing it, and updated protocol specs and
64 the server implementation. Protocol TODO #10. The affected
65 file is silcd/command.c.
67 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
68 generic reply to a generic request (REQUEST flag), and
69 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
70 way. A draft-riikonen-silc-flags-payloads-00.txt is written
71 to define the payload for DATA flag. Added the flags to
72 the implementation. Protocol TODO #9. Affected file is
73 lib/silccore/silcchannel.h.
75 Changed the client library to return the message length
76 to application as well in the channel_message and private_message
77 client operations. Affected files are
78 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
79 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
80 and lib/silcclient/client_ops_example.c.
82 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
83 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
84 the channel. Updated protocol specs and impelemented this
85 to client and server. Protocol TODO #6. Affected files are
86 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
87 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
89 Added new options m and M to CMODE command in Irssi SILC
90 client to set these modes.
92 * Deprecated all administrative commands from SILC protocol
93 since they are highly implementation specific commands.
94 Updated protocol specs. Moved the old commands in
95 implementations to private range of command types. Affected
96 files are silcd/command.c, lib/silcclient/command.c and
97 lib/silcclient/command_reply.c. Protocol TODO #8.
99 * Fixed a bug in server where sending unknown command crashes
100 the server. Affected file silcd/command.c.
102 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
104 * Added SILC_PROTOCOLVERSION macro to check protocol version
105 of a socket connection. The affected file is
106 lib/silcutil/silcsockconn.h.
108 * Added better error logging in rekey protocol. Affected file

112 file lib/silcske/payload.c.
114 * Fixed the rekey protocol with PFS, which was totally broken.
115 Affected file silcd/protocol.c.
117 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
119 * Some client implementations quit network by doing first LEAVE
120 and then immediately SIGNOFF (like Bombyx). We now do check
121 after a short time after LEAVE notify and check whether the
122 client is still valid after LEAVE, and if not we remove it from
123 cache. Affected file is lib/silcclient/client_notify.c.
125 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
127 * Merged version 1.1.4 of zlib. Even if it not currently in use,
128 it's good not to have security holes here.
130 * Fixed a negative refcount situtuation for the config context.
131 Affected file is silcd/serverconfig.c.
133 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
135 * ROBOdoc documented lib/silcutil/silcutil.h.
137 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
139 * Optimized even more the SilcPacketContext structure. Now
140 totally saved 16 bytes of memory per context after optimization.
141 Affected files are lib/silccore/silcpacket.[ch].
143 * Made strict checks for valid SILC IDs. Affected file is
144 lib/silccore/silcid.c.
146 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
148 * Changed the object argument for silc_cipher_register,
149 silc_hash_register, silc_hmac_register and silc_pkcs_register
150 to const. Affected files are lib/silccrypt/silccipher.[ch],
151 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
153 * Changed the silc_get_username and silc_get_real_name to
154 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
156 * Fixed the Irssi SILC Client to use the silc_get_username and
157 silc_get_real_name insted of glib routines since the glib
158 routines only corrupt stack. Fixes the Irssi SILC to work in
159 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
161 * Fixed the Irssi to not use g_get_home_dir since it crashes
162 or returns garbage on cygwin and corrupts stack. Added function
163 get_home_dir to Irssi routines. Affected files are
164 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
166 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Made some structure optimizations. SFTP memory FS MemFSEntry
169 entry structure. Optimized SilcTask structure. Optimized
170 SilcPacketContext structure.
172 Affected files lib/silcsftp/sftp_fs_memory.c,
173 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
175 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
177 * And yet again reverted back the config thing since Johnny
178 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
181 * Fixed memory leaks from config object. Affected files are
182 silcd/serverconfig.[ch].
184 * Added support for adding new connections to the server in rehash.
185 After rehash they take effect.
187 Added support for changing the maximum allowed connections in
188 rehash. The number can grow but going smaller is not supported.
190 Added function silc_server_num_sockets_by_remote to the
191 silcd/server_util.[ch].
193 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
195 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
197 * Added preliminary checking during config parsing for a valid
198 public/private key and removed further checks in the code.
199 Affected files are silcd/serverconfig.[ch], server.c.
201 * Moved functions silc_server_drop() and silc_server_daemonise()
202 from server.c to silcd.c since they are stricly related to
203 the application activity.
205 * Reverted a small part of the automatic ref/unref since
206 it caused a double unref in some situations. Affected
207 files are silcd/silcd.[ch], server.c, serverconfig.c.
209 * Added some .cvsignore files in the lib directory.
211 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
213 * Fixed silc_net_gethostbyaddr to correctly resolve by
214 address. Affected file lib/silcutil/silcnet.c.
216 * Fixed the notify relaying to client. The HMAC to be used
217 with relayed packets ws wrong and caused decryption failure
218 at the client end. Affected file is silcd/packet_receive.c.
220 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
222 * Created new branch silc_protocol_1_0_branch.
224 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
226 * Changed the silc_server_config_* routines to be SilcServer
227 independent. They are now officially application specific code
228 and not part of generic server implementation. Affected files
229 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
231 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
233 * Added automatic referencing of config context in the
234 silc_server_config_alloc, and automatic unreferencing in the
235 silc_server_config_destroy. Affected files are
236 silcd/serverconfig.[ch], silcd/silcd.c.
238 * Fixed the silc_log_quick handling in the logging routines.
239 It didn't log quickly when it was TRUE. Affected file is
240 lib/silcutil/silclog.c. Also the flush delay was set even
241 if it was 0 in config file. Affected file is
242 silcd/serverconfig.c.
244 * Added support for changing key pair of the server in rehash.
245 Affected file silcd/server.c.
247 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
249 * Fixed the TOPIC_SET notify to not cras. It changed the topic
250 too early, before getting the channel entry. Affected file
251 is silcd/packet_receive.c.
253 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
255 * Added functions silc_server_config_[ref/unref], these are used
256 to prevent that the config object is destroyed.
258 No longer directly affect global variables silc_log_quick and
259 silc_log_delay, they are first cached inside the config object
260 and then applied with silc_server_config_setlogfiles().
262 silc_server_config_set_defaults() is now internal to
263 serverconfig.c, there are no reasons to show this internal stuff
266 Affected files are silcd/serverconfig.[ch].
268 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
269 fprintf's to stderr, since some code may be executed again after
270 the server went into the background. Affected files are
273 * Added rehash support. Added function silc_server_rehash() that
274 will perform all the basic tasks of the rehashing procedure.
276 * Added command line option `-x, --hexdump'. This will enable the
277 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
278 The option `--hexdump' implies `--debug'.
280 * Fixed a bad bug in the logging APIs (silcutil library) where
281 the application would crash after calling silc_log_reset_all().
283 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
285 * Fixed the KICKED notify handling in client library to
286 correctly remove the channel and all entries from the
287 channel when I was kicked. This bug crashed the client.
289 Fixed yet another but in KICKED notify handling to remove
290 the kicked client correctly from the channel.
292 Affected file is lib/silcclient/client_notify.c.
294 * Fixed a minor bug in looking up correct client entry
295 in KICKED notify in server. Affected file is
296 silcd/packet_receive.c.
298 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
299 sources correctly to distribution. Fixes --with-gmp option.
301 * Removed the manual rehashing from ID Cache, and changed it
302 to use the SILC Hash Table's auto rehash feature. Affected
303 file is lib/silccore/silcidcache.c.
305 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
307 * Fixed a bug in the silc_client_nickname_format function that
308 handles the multiple same nickname formatting. Two clients
309 with same nickname caused problems after the first one left
310 and rejoined. It didn't format the nickname correctly.
311 Affected file is lib/silcclient/idlist.c.
313 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
315 * Don't change the topic if olod topic is same as new one.
316 Affected file is silcd/packet_receive.c.
318 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
320 * Added cross-reference support to the SILC Documentation
321 generator. All types across all HTML files are now cross-
322 referenced. Affected files util/robodoc/generator.c and
323 scripts/silcdoc/silcdoc.
325 * Added file lib/silcutil/silctypes.h to include all the
326 arithmetic type definitions and some macros. Removed
327 includes/bitmove.h and moved macros to silctypes.h.
329 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
331 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
333 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
335 * Added `type' argument to silc_id_payload_parse_id function which
336 now returns the type of the ID to the sent pointer. Affected
337 file is lib/silccore/silcid.[ch].
339 * Added check for CMODE_CHANGE notify type that mode change is
340 allowed by the sender. Affected file silcd/packet_receive.c.
342 * Added check for CUMODE_CHANGE notify type that mode change is
343 allowed by the sender. Affected file silcd/packet_receive.c.
344 Added the ID type as CUMODE_CHANGE notify type as argument
345 to the `notify' client operation. Affected files are
346 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
348 * Added function silc_client_add_server to the client library.
349 Added support for resolving also channel and server info when
350 received unknown entity in notify packet. Affected files are
351 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
353 * Added function silc_command_get_status to return the command
354 status from the command reply's argument payload. Affected files
355 are lib/silccore/silccommand.[ch].
357 * Added check for KICKED notify type that the kicking is
358 allowed by the client. Affected file silcd/packet_receive.c.
360 * Created function silc_get_input which can be used to get input
361 (echo on or off) from user on command line. Affected files are
362 lib/silcutil/silcutil.[ch].
364 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
366 * Optimized silc_server_packet_relay_to_channel function.
367 Added new function silc_channel_message_payload_encrypt which
368 can be called directly if channel message payload needs to
369 be encrypted and is already encoded (no need to call _encode
370 function). Packet relaying is now done by router without any
371 extra memory allocations. Affected files are
372 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
375 * Fixed the INVITE notify handling. It took wrong arguments
376 as invite list and invite delete. Affected file is
377 silcd/packet_receive.c.
379 * Added check for TOPIC_SET notify type that the topic change is
380 allowed by the client. Affected file silcd/packet_receive.c.
382 * Added check for INVITE notify type that inviting is allowed by
383 the client. Affected file silcd/packet_receive.c.
385 * Changed the silc_server_client_on_channel to return the
386 SilcChannelClientEntry as well. Moved the function
387 silc_server_check_cmode_rights to server_util.[ch].
388 Affected files are silcd/server_util.[ch], silcd/command.c.
390 * Added function silc_server_check_umode_rights to check whether
391 changing client's user mode is allowed. Added check for
392 UMODE_CHANGE notify type that the umode change is allowed
393 by the client. Affected files are silcd/server_util.[ch],
394 silcd/packet_receive.c and silcd/command.c.
396 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
398 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
399 ID length. It ignored that ID can be IPv6 based as well.
400 Affected file lib/silccore/silcpacket.h.
402 * Fixed the silc_id_id2str and silc_id_str2id to take the
403 IPv6 address offset's into consideration. Affecte file is
404 lib/silccore/silcid.c.
406 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
408 * Fixed the internal Unix scheduler functions to check for
409 NULL context they may receive. The affected file is
410 lib/silcutil/unix/silcunixschedule.c.
412 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
414 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
415 can specify different directory with --home command line
416 parameter. Affected files irssi/src/silc/core/client_ops.c,
419 * SILC-specific commands aren't now executed if the active server
420 isn't of SILC-type, so there won't be problems with having
421 IRC and SILC protocol support in same client. Affected files
422 irssi/src/silc/core/silc-channels.c, silc-servers.c,
425 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Improved the signal support in SILC Schedule. Added new
428 function silc_schedule_signal_call which is used by application
429 to mark a signal to be called. It is now safe to perform
430 any kind of tasks in signal callbacks since it is guaranteed
431 that the application specified signal callback is called
432 after the signal is over. Affected files are
433 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
435 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
437 * Added `name' field to SilcChannelPrivateKey to represent
438 application given name for the key. Moved also the context from
439 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
440 Added the `name' argument also to the function
441 silc_client_add_channel_private_key.
443 Added function silc_client_current_channel_private_key to set the
444 current channel private key in use.
446 Added "change" command to KEY command which can be used to change
447 the current channel private key. Bound the command also to
450 Also affected files lib/silcclient/client_channel.c,
451 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
453 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Added silc_rng_get_byte_fast function in to the
456 lib/silccrypt/silcrng.[ch].
458 * Changed the interface of silc_packet_assemble and the
459 silc_packet_send_prepare. If silc_packet_assmble is now
460 called the application does not call silc_packet_send_prepare
461 because the library will call it automatically. These
462 interfaces now also return a reference to the outgoing buffer
463 which includes the assembled packet, which the application can
464 use to encrypt the packet.
466 Affected files are lib/silccore/silcpacket.[ch],
467 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
468 silcd/packet_send.c, server_backup.c and packet_receive.c.
470 * Fixed a packet sending bug on very high load, where outgoing
471 packet queue wasn't handled correctly and packets got corrupted.
472 Affected files are lib/silcutil/*/silc*sockconn.c,
473 lib/silcclient/client.c and silcd/server.c.
475 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Added macro SILC_PACKET_DATALEN which can be used during
478 packet assembling to check whether the data to be added to
479 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
480 len is truncated until it fits it.
482 Added checks for maximum length of channel message payload and
483 private message payload also.
485 Added checks for maximum packet length in server and in
488 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
489 lib/silcclient/client.c, lib/silccore/silcchannel.c and
490 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
491 lib/silcclient/client_prvmsg.c.
493 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
495 * Added silc_server_packet_queue_purge call to the
496 silc_server_disconnect_remote to assure that all data in the
497 queue before disconnecting is sent to the network. Affected
500 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
502 * Added the deleting of server's own ID cache entry to the
503 silc_server_free function. Free also everything else that
504 has been allocated in silc_server_init. The affected file
507 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
509 * Added functions silc_parse_version_string, silc_version_to_num,
510 and silc_ske_parse_version to parse SILC protocol style version
511 strings. Affected files lib/silcutil/silcutil.[ch] and
512 lib/silcske/silcske.[ch].
514 * Added new configuration params: version_protocol, version_software
515 and version_software_vendor to specify what version the remote
516 host must at least be to be able to connect to server. The vendor
517 string can be regex matched too. Added new function
518 silc_server_connection_allowed to check maximum number of allowed
519 connections, and allowed versions for incoming connections.
520 Affected files are silcd/server.c, server_util.[ch] and
523 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
525 * Added preliminary support for signals in scheduler. The
526 signals we care about are now blocked always when the scheduler
527 is locked. This way we can synchronise the use of signal with
528 scheduler. It is guaranteed that when signal occurs the scheduler
529 is not locked, and thus new tasks can be safely added to the
532 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
533 to silc_schedule_internal_init and silc_schedule_internal_uninit.
534 Added new platform specific routines
535 silc_schedule_internal_signals_[un]block and
536 silc_schedule_internal_signal_[un]register.
538 Added new functions to SILC Schedule API:
539 silc_schedule_signal_[un]register. Each signal that application
540 is going to use should be registered to the scheduler.
542 Affected files are lib/silcutil/silcschedule.[ch],
543 lib/silcutil/*/silc*schedule.c.
545 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
547 * Check for unauthenticated client and server in the
548 silc_server_new_client and silc_server_new_server functions.
549 Affected file silcd/packet_receive.c.
551 * Added function silc_string_is_ascii to check whether given
552 string is 7-bit ASCII string. Affected files are
553 lib/silcutil/silcutil.[ch].
555 * Added function silc_id_is_valid_server_id into the
556 silcd/serverid.c and added checking for valid Server ID's in
557 silc_server_new_server. The Server ID must always be based
558 on the server's public IP address.
560 * Added logging of DISCONNECT packet message in the server.
561 Affected file silcd/server.c.
563 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
565 * Changed all library interfaces that use Global RNG to also
566 accept SilcRng as argument. Affected files are
567 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
568 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
569 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
570 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
573 * Added function silc_pkcs_generate_key to the
574 lib/silccrypt/silcpkcs.[ch] for applications so that they
575 don't need to do pkcs->pkcs->init calls anymore.
577 * Remove SilcSocketConnection from the SFTP API since it really
578 wasn't needed there. The application has the information
579 saved in its contexts anyway and the SFTP layer doesn't need
580 know about it. Affected files lib/silcsft/silcsftp.h and
581 lib/silcsftp/sftp_[server/client].c.
583 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

587 lib/silcutil/silcutil.c.
589 * On EPOC the global crypto module lists are not used at all
590 in the crypto library. Added support for using the constant
591 algorithm list on EPOC. Affected files are
592 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
595 * Fixed the handling of third parameter of KICKED notify, since
596 it was mistakenly updated to SILC Protocol 1.0 even though it
597 is to be included in 1.1. Since it is not in 1.0 it is not
598 mandatory, and this fix now handles it only if it is provided,
599 and it is not error if it is not provided. Affected file
600 lib/silcclient/client_notify.c.
602 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
605 client. Affected file irssi/src/silc/core/client_ops.c.
607 * Merged with Irssi 0.8.4 from irssi.org CVS.

612 sending any messages. Fixes a crash, but doesn't fix some
613 other underlaying bug that is lurking there. Affected
614 file silcd/packet_send.c.
616 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
618 * $usermode, $cumode and $cumode_space expandos shouldn't do
619 anything with non-SILC server records. Affected file
620 irssi/src/silc/core/silc-expandos.c
622 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
624 * Fixed the silc_net_check_[host/local]_by_sock to support
625 IPv6 bound sockets as well. Now they can return IPv6 addresses
626 as well. Affected file lib/silcutil/silcnet.c.
628 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
629 Affected lib/silcutil/unix/silcunixnet.c.
631 * Fixed ID rendering (at least on some platforms, not NetBSD)
632 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
634 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Added silc_hash_public_key and silc_hash_public_key_compare
637 functions to be used with SilcHashTable. They can be used to
638 hash public keys and compare public keys in hash table. Affected
639 file lib/silcutil/silcutil.[ch].
641 * Added support for specifying multiple public keys for Client
642 connection section in server configuration file. This makes it
643 possible to accept multiple public keys from same host, or to
644 make a section that accepts any incoming host, and have the
645 accepted public keys listed in the section.
647 Added functions silc_sever_[find/get]_public_key, added the
648 support for this actually to all connection sections but only
649 the Client section is currently allowed to specify multiple
652 Affected files are silcd/server.c, server_internal.h,
653 command.c, protocol.c, server_util.[ch], packet_receive.c.
655 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

659 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
661 * If silc_debug is TRUE, also output standard logging messages
662 to stderr with the debug output.
664 Made silc_log_reset_all() flushing all channels before returning.
665 Also fixed some documentation typos.
667 Affected files are lib/silcutil/silclog.[ch].
669 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
671 * Fixed the server to check correctly the amount of connections
672 from single host, by checking also the type of the connection.
673 Fixed also the comparison of number of connections and number
674 of allowed connections. Affected files are silcd/server.c,
677 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
679 * Fixed the USERS command reply to save the user's mode on the
680 channel as well. Fixed JOIN command reply to check whether a
681 client is on channel already and not join it twice. Affected
682 file lib/silcclient/command_reply.c.
684 * Added new file silc-expandos.c into irssi/silc/core/ to return
685 various stuff for various signal for the statusbar etc. updating.
686 Now Irssi SILC client prints channel user modes etc. on the
689 * The user mode (like server/router operator changes) is now shown
690 on the Irssi SILC client's statusbar. The affected files are
691 irssi/src/silc/core/client_ops.c, silc-expandos.c.
693 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>

701 * Fixed -S option parsing in Irssi SILC Client. Affected file
702 irssi/src/silc/core/silc-core.c.
704 * Added silc_buffer_alloc_size function. Affected file is
705 lib/silcutil/silcbuffer.h.
707 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

725 * Removed 0.6.x backwards support.
727 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Changed all integer type names:
730 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
731 to avoid collisions with other libraries using same type names
734 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
736 * Added `prefer_ipv6' argument to the functions
737 silc_net_gethostbyname[_async]. If it is TRUE it will return
738 IPv6 address over IPv4. If FALSE IPv4 address is returned
739 even if IPv6 address was found. Affected files
740 lib/silcutil/silcnet.[ch].
742 * Added support silc_net_create_connection[_async] to fallback
743 to IPv4 address if IPv6 address could not be used (like if

755 * Added automatic extern "C" { ... } for C++ compilers so the
756 application does not need to define them. Affected file
757 includes/silcincludes.h.
759 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
760 old name went against naming convention. Applications now
761 include "silcclient.h" instead of "clientlibincludes.h".
762 Removed includes/clientlibincludes.h, it is redundant now.
764 * Renamed includes/version.h to silcversion.h.
766 * Added really preliminary support for OS/2 into the util
767 library. Only thread & mutex API is implemented, others
768 are still to be implemented. Created the lib/silcutil/os2/
769 directory. Created also file includes/silcos2.h.
771 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
773 * Added preliminary BeOS support into the util library.
774 Created lib/silcutil/beos/, and implemented all the needed

780 * Added proper initializations to silc's irssi code, so it's
781 now possible to load it as module. Affected files
782 irssi/src/silc/core/silc-core.c,
783 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
785 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

800 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
802 * Added `user_count' to the SilcChannelEntry which now tells the
803 number of users on the channel. The user count is now saved
804 in normal server of global channels as well. Affected files
805 silcd/server.c, idlist.h, packet_receive.c and command.c.
807 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

818 client_entry->channels hash table everytime nick is changed.
819 Affected file lib/silcclient/client.c.
821 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
823 * ROBOdoc documented the lib/silcske/silcske.h, and improved
824 the SKE interface a bit.
826 * Fixed padding problem in PKCS#1. The padding was not actually
827 random since the random number generator was used incorrectly.
828 This security bug affects only when encrypting with PKCS#1, and
829 it is not currently used at all in SILC. SILC only use signing
830 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
832 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

849 Optimized the use of SKE Mutual flag usage. Use it only
850 if connection authentication protocol is not based in public
853 Renamed all SilcServerConfigSection* to SilcServerConfig*
854 to have a bit shorter names.
856 Affected files silcd/serverconfig.[ch], server.[ch], and
859 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

877 * Removed type casts from silc_calloc(), conforming to the
878 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
880 * Removed param_name member from client, server, and router
881 section structs, now identifying the param directly.
883 Added CONFIG_FREE_AUTH macro in config file parsing.
885 Affected files are silcd/serverconfig.[ch].
887 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>

893 Affected files irssi/src/silc/core/silc-core.c,
894 irssi/src/fe-text/silc.c.
896 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
898 * Added new configuration options and blocks:
899 keepalive_secs, reconnect_count, reconnect_interval,
900 reconnect_interval_max, reconnect_keep_trying and
901 require_reverser_lookup. Added ConnectionParam block, and
902 implemented the connection parameters when connecting as
903 initiator and when accepting connections as responder.
905 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
906 whether given configuration value has been given already.
908 Affected files silcd/serverconfig.[c], server.[c].
910 * Splitted the doc/example_silcd.conf.in. Separated the crypto
911 algorithm parts and created new file silcalgs.conf, that
912 is now included from the example_silcd.conf.in.
914 * Optimized the silc_server_connect_to_router_second to take
915 the connection configuration object from the SilcServerConnection
916 object instead of finding it during the connecting phase.
917 Added the configuration object to SilcServerConnection struct.
918 Affected files silcd/server_internal.h, server.c.
920 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
922 * Add the client on channel after it was resolved at the
923 channel message receiving, and it was not already on the
924 channel. Affected file lib/silcclient/client_channel.c.
926 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

932 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
934 * Unified the serverconfig.[ch]'s helper function interface.
935 Affected file silcd/serverconfig.[ch].
937 * Removed doc/example_silc.conf.in since it is redundant.
938 The make install will now install irssi/silc.conf file.
940 * Added new Passphrase and Publickey authentication methods to
941 config file, allowing both public key and passphrase based
942 authentication to be set at the same time.
944 Added `prefer_passphrase_auth' setting in config file which
945 can be used to set to prefer passwd auth if both passwd and
946 public key is set. If not set, public key is preferred.
947 This has effect only when being initiator (responder will try
950 Added support for authentication with passphrase and public key
951 at the same time. The passphrase is tried first always since
952 it is faster to check.
954 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
956 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1002 * Fixed the file transfer's key agreement payload to include
1003 zero port also if the hostname is NULL because it could not
1006 Call file transfer monitor callback now also if error occurs
1007 during key agreement protocol.
1009 Changed the silc_client_file_send interface to return the
1010 SilcClientFileError instead of session id. The session ID
1011 is returned into pointer provided as argument.
1013 Check that the file exists locally before sending the
1014 file transfer request at all.
1016 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1018 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1024 irssi/src/silc/core/silc-channels.c.
1026 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1027 SILC_LOG_WARNING to give out Warning and not Error. Affected
1028 file lib/silcutil/silclog.c.
1030 * Fixed the channel message payload decryption in the function
1031 silc_channel_message_payload_decrypt to not modify the original
1032 buffer before it is verified that the message decrypted
1033 correctly. Otherwise, next time it is called with correct
1034 channel key it won't encrypt since the payload is corrupted.
1035 Affected file lib/silccore/silcchannel.c.
1037 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1050 the table with foreach callback. The current entry may
1051 become invalid in the callback but it was referenced after
1052 the callback returned.
1054 Do not allow auto rehashing of hash table during the
1055 silc_hash_table_foreach operation, for same reasons as it is
1056 not allowed for SilcHashTableList. Affected files are
1057 lib/silcutil/silchashtable.[ch].
1059 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1067 * Fixed private message handling. It used some old code that
1068 caused the client to crash. Affecte file is
1069 lib/silcclient/client_prvmsg.c.
1071 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1073 * Added function silc_client_add_channel,
1074 silc_client_replace_channel_id, and removed functions
1075 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1076 from client library.
1078 * Added cross reference of the joined channels to the
1079 SilcClientEntry, and changed the SilcChannelEntry's
1080 users list to SilcHashTable. The affected files are
1081 lib/silcclient/idlist.[ch].
1083 * Fixed a bug in hash table tarversing. While the hash table
1084 is traversed with SilcHashTableList the table must not be
1085 rehashed. It is now guaranteed that auto rehashable tables
1086 are not rehashed while tarversing the list. Also defined that
1087 silc_hash_table_rehash must not be called while tarversing
1088 the table. Added function silc_hash_table_list_reset that must
1089 be called after the tarversing is over. The affected files are
1090 lib/silcutil/silchashtable.[ch].
1092 * Changed all hash table traversing to call the new
1093 silc_hash_table_list_reset in server and in client library.
1095 * Added function silc_client_on_channel to return the
1096 SilcChannelUser entry if the specified client entry is joined
1097 on the specified channel. This is exported to application as
1098 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1100 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1102 * Fixed founder regaining problem with JOIN command on normal
1103 server. The notify for mode change must be sent always and
1104 not only if !cmd->pending. Affected file silcd/command.c.
1106 * Fixed the WHOWAS command's reply sending to support the
1107 lists correctly. Affected file silcd/command.c.
1109 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1111 * When sending JOIN command to router for processing the
1112 sender's old command identifier was not saved back to the
1113 sender's command context, fixed now. The affected file is
1116 * Create the key in JOIN command of the router did not return
1117 the channel key, added check for this. Affected file is
1120 * Fixed a channel ID update bug in JOIN command reply. Do
1121 not directly upgrade the ID but call the function
1122 silc_idlist_replace_channel_id if the ID was changed.
1123 Affected file silcd/command_reply.c.
1125 * Fixed memory leaks from command calling if it would fail.
1126 Affected file silcd/command.c.
1128 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1130 * Applied patches from cras:
1132 Memory leak fixes around libaries, irssi window resize fix,
1133 new silclist.h and silcdlist.h, all extern inline changed to
1136 * Removed dotconf from lib/dotconf, not needed anymore.
1138 * Removed TRQ from lib/trq, not needed anymore.
1140 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1141 with server connections. Later this will be configurable
1142 in config file after new config file is done. Affected file
1145 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1147 * Fixed a crash in server related to channel announcements.
1148 Affected file silcd/server.c.
1150 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed memory leaks in silc_server_create_new_channel*
1153 functions. Affected file silcd/server.c.
1155 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1156 which ID was changed. This way the router will send the
1157 user list for the channel again, and server won't be in
1158 desync in some rare circumstances. Affected file is
1159 silcd/packet_receive.c.
1161 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1163 * Check for NULL socket pointer in the function
1164 silc_server_packet_send_to_channel_real. Affected file
1165 silcd/packet_send.c.
1167 * Fixed the BAN notify handling to correctly remove ban
1168 list. Affected file silcd/packet_receive.c.
1170 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1172 * Fixed some header addition to Toolkit distribution in
1173 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1175 * Added lib/silcclient/client_ops_example.h as an template
1176 file for application programmers to quickly start using
1177 the SilcClientOperation functions in their application.
1178 Updated the lib/silcclient/README as well to tell about this
1179 nice file made available.
1181 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1183 * Call silc_server_remove_from_channels when removing client
1184 entry when NO_SUCH_CLIENT_ID was received. Affected file
1185 is silcd/command_reply.c.
1187 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1189 * Added server & router operator statistics updating. Affected
1190 file silcd/packet_receive.c and silcd/command.c.
1192 * Fixed the SERVER_SIGNOFF notify handling on normal server
1193 not to save the history information for clients. Same was
1194 fixed earlier in remove_clients_by_server function, but not
1195 here. Affected file silcd/packet_receive.c.
1197 * Raised the default connection-retry count from 4 to 7 in
1198 server. Affected file silcd/server.h.
1200 * Cancel any possible reconnect timeouts when we start the
1201 key exchange. Affected file silcd/server.c.
1203 * Do not reconnect on connection failure when SCONNECT was
1204 given. Affected files silcd/server.[ch].
1206 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1208 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1210 * Fixed the NICK command to always give the unformatted
1211 nickname to the one giving the NICK command. If unformatted
1212 nickname is cached already it will be formatted and the
1213 local entry will always get the unformatted nickname.
1214 Affected file lib/silcclient/idlist.c.
1216 * Fixed some double frees from client library commands.
1217 Affected file is lib/silcclient/command.c.
1219 * Fixed CUMODE command in server to assure that no one can
1220 change founder's mode than the founder itself, there was a
1221 little bug. Affected file silcd/command.c.
1223 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1225 * Removed the SilcClientCommandDestructor from the client
1226 libary, it is not needed anymore. Affected files are
1227 lib/silcclient/silcapi.h, command[_reply].[ch],
1228 client_notify, idlist.c.
1230 * Fixed GETKEY command to first resolve client, and then
1231 resolve the server only if the client was not found, instead
1232 of resolving both at the same time. Affected file is
1233 lib/silcclient/command.c.
1235 * Added silc_client_start_key_exchange_cb and lookup the
1236 remote hostname and IP address before starting the key
1237 exchange with server. The affected file is
1238 lib/silcclient/client.c.
1240 * The server's public key is now saved using the IP address
1241 of the server and not the servername for the filename.
1242 The hostname public key filename is checked as an fall back
1243 method if the IP address based filename is not found.
1245 Fixed the GETKEY command to save the fetched server key
1246 in correct filename.
1248 Print the remote server's hostname now when new key is
1249 received during connection process. Affected file is
1250 irssi/src/silc/core/client_ops.c.
1252 * Return always our own public key to the client if it asks
1253 for it with GETKEY command. Affected file silcd/command.c.
1255 * Removed the use_auto_addr variable from default config
1256 file since it was in wrong section. Affected file is
1259 * Fixed TOPIC_CHANGE notification to not route it when it
1260 was sent using silc_server_send_notify_to_channel function.
1261 Affected file silcd/command.c.
1263 * Fixed silc_server_send_notify_kicked to send the kicker's
1264 Client ID also, it was missing. Affected files are
1265 silcd/command.c, silcd/packet_send.[ch].
1267 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1269 * Do not save client history information in SERVER_SIGNOFF.
1270 Fixes the bug in normal server that it does not detect
1271 the client becoming valid after the server becomes back
1272 online. Affected file silcd/server_util.c.
1274 * Added `sock_error' field into the SilcSocketConnection
1275 context. When error occurs during socket operation (read
1276 or write) the error is saved. Added also new function
1277 silc_socket_get_error to return human readable socket error
1278 message. Affected files are lib/silcutil/silcsockconn.[ch],
1279 lib/silcutil/unix/silcunixsockconn.c, and
1280 lib/silcutil/win32/silcwin32sockconn.c.
1282 * The server now prints the socket error message in the
1283 signoff for client. Affected file silcd/server.c.
1285 * Fixed the `created' channel information sending from router
1286 to server in JOIN command. Checks now whether the channel
1287 really was created or not and set it according that.
1289 Fixed the JOIN command to use the client entry's current
1290 ID during the joining procedure instead of the one it sent
1291 in the command (it is checked though), since it can change
1292 between the packet processing and command processing, and
1293 would just case unnecessary pain in the client end. Affected
1294 file silcd/command.c.
1296 * Fixed a channel key payload sending to use correct channel
1297 ID when the server was forced to change the channel's ID by
1298 router. Router sent the key payload with the old Channel ID.
1299 Affected file silcd/packet_receive.c.
1301 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1303 * Call silc_server_save_channel_key only if the key payload
1304 was provided in the JOIN command's command reply. Affected
1305 file silcd/command_reply.c.
1307 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1309 * Fixed silc_mp_sizeinbase to return the value correctly with
1310 MPI. Affected file lib/silcmath/mp_mpi.c.
1312 * Fixed the stop_server signal to correctly stop the scheduler
1313 and gracefully stop the server when SIGTERM or SIGINT signals
1314 are received. Affected file silcd/silcd.c.
1316 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1318 * Simple handling of TERM and HUP signals. Also added some log
1319 flushing call around. Affected file is
1322 * Fixed small bugs in silclog.c. Now buffering output will take
1323 effect after 10 seconds since startup: This will ensure that
1324 no important startup messages are lost. Also output redirection
1325 will preserve original format ([Date] [Type] message).
1326 Affected file is lib/silcutil/silclog.c.
1328 * Added two options to the config file, in the logging section:
1329 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1330 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1332 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1334 * Do not print the warning about log files not being initialized
1335 more than once to avoid excess logging. Affected file is
1336 lib/silcutil/silclog.c.
1338 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1339 the SIM copying in make install in Makefile.am.pre.
1341 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1343 * Rewritten silclog APIs. Globally interesting changes follows:
1344 silc_log_set_files() changed to silc_log_set_file().
1345 silc_log_set_callbacks() changed to silc_log_set_callback().
1346 ROBOdoc documented silclog header file.
1347 SilcLogCb now returns bool to wether inihibit the default
1348 handler or not (to keep the old behaviour return always TRUE).
1349 The new APIs should also fix the problem of the
1350 silcd_error.log file that was written in the current directory.
1353 Log files streams will remain opened after silc_log_set_file()
1354 call, means less CPU usage notably on high traffic servers.
1355 File streams are now full buffered, and flushed to the disk
1356 every 5 minutes, lesses HD activity and CPU usage.
1357 Messages can be redirected, allowing admins to configure
1358 one single logfile for all server messages.
1359 the silc_log_quick global variable to activate fast-logging.
1360 Affected files lib/silcutil/silclog.[ch]
1362 * Changed some code to conform new silclog APIs. Affected
1363 files are doc/example_silcd.conf.in, silcd/server.c
1364 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1367 * Fixed a memory leak that could occur in some situations.
1368 Affected file silcd/serverconfig.c.
1370 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1372 * Added the silc_client_del_client to remove the client from
1373 all channels as well. Affected file lib/silcclient/idlist.c.
1375 * Fixed the client library to correctly remove the client
1376 from all channels when the client entry is being destroyed.
1377 Affected file lib/silcclient/client_notify.c, command.c.
1379 * Added auto-nicking support to the client library. If the
1380 applicatio now sets client->nickname it will be sent to the
1381 server after connecting by the library. This way for example
1382 SILCNICK (or IRCNICK) environment variables will have effect
1383 and always change the nickname automatically to whatever
1384 it is wanted. Affected file lib/silcclient/client.[ch].
1386 * Renamed silc_server_command_bad_chars to the
1387 silc_server_name_bad_chars and moved it to the
1388 silcd/server_util.[ch]. Added also new function
1389 silc_server_name_modify_bad to return nickname that
1390 includes bad characters as new nickname without those
1391 bad characters. This check and modify is now used in
1392 silc_server_new_client when the username is initially set
1393 as nickname, so it must be checked to be valid nickname.
1394 Affected file silcd/packet_receive.c.
1396 * The nickname length is now taken from the packet for real
1397 and not trusted to strlen() since it clearly can return
1398 wrong length for nickname including bad characters. This
1399 also applies to channel names. Affected file silcd/command.c.
1401 * Removed the lib/silcsilm/modules directory. Modules are now
1402 compiled into the lib/silcsim. Fixed the copying of the
1403 modules to follow symbolic links in Makefile.am.pre.
1405 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1407 * Fixed silc_string_regexify list creation. Fixes bugs with
1408 BAN and INVITE commands in server. The affected file is
1409 lib/silcutil/unix/silcunixutil.c.
1411 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Removed the command destructor entirely from the server's
1414 command and command reply routines. It is not needed, and
1415 its usage was buggy and caused crashes. Affected files are
1416 silcd/command[_reply].[ch].
1418 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Cancel protocol and NULL sock->protocol if timeout
1421 occurred during protocol. Affected file silcd/server.c.
1423 * Cancel protocol timeouts always before calling the final
1424 callback, to assure that after final callback is called
1425 no other state will be called for the protocol anymore.
1426 Affected file silcd/protocol.c.
1428 * Print error log if incoming connection configuration could
1429 not be found. Affected file silcd/server.c.
1431 * Fixed JOIN command to correctly save the founder mode
1432 to the client on normal SILC server, when the channel
1433 was created by the router. Affected file silcd/command.c.
1435 * Fixed LIST command (hopefully) to send correct reply
1436 packets. Affected file silcd/command.c.
1438 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * The silc_packet_receive_process now returns FALSE if the
1441 read data was invalid packet, and TRUE if it was ok.
1443 The server now checks that if unauthenticated connection
1444 sends data and its processing fails the server will close
1445 the connection since it could be a malicious flooder.
1447 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1449 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Make sure the warning about error opening a log file is
1452 printed only once and not everytime it fails (produces
1453 too much useless log). Affected file lib/silcutil/silclog.c.
1455 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1457 * Made the silc_server_daemonise() function more readable.
1458 Affected file silcd/server.c.
1460 * Pid file is now optional, the user may comment it out from
1461 the config file. Removed define SILC_SERVER_PID_FILE, we
1462 don't need a default any longer. Affected file
1463 configure.in.pre, lib/Makefile.am.pre.
1465 * Make some use of the pid file. The server now dies at startup
1466 if it detects a valid pid file on his path. The server would
1467 die anyway in this circumstance, because of the bind() failure.
1468 Affected file silcd/silcd.c.
1470 * No longer compiling lib/dotconf.
1472 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Fixed JOIN command parsing not to crash. Affected file
1475 lib/silcclient/command.c.
1477 * Fied the NICK_CHANGE notify to add the new client entry
1478 even it is resolved. This removes an <[unknown]> nick
1479 thingy bug in the client. Affected file is
1480 lib/silcclient/client_notify.c.
1482 * Do not try to allocate 0 bytes (efence does not like it)
1483 in lib/silccore/silccomand.c when encoding payload.
1485 * Do not take IRCNICK as nickname in Irssi SILC client since
1486 it is not possible to set nickname before hand connecting
1487 the server (TODO has an entry about adding auto-nicking
1490 * Changed the silc_server_command_pending to check whether
1491 there already exists an pending entry with the specified
1492 command, command identifier and pending callback. This is
1493 to fix IDENTIFY and WHOIS related crashes that may register
1494 multiple pending commands with same identifier. Affected
1495 file silcd/command.c.
1497 * Fixed the server to reconnect to the router even if it
1498 was already reconnecting and EOF was received. This to
1499 fix a possibility that the server wouldn't ever try to
1500 auto-reconnect to the router. Affected file silcd/server.c.
1502 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Fixed the server's password authentication to use the
1505 length of the locally saved password, and not the one
1506 sent in the packet. Affected file silcd/protocol.c.
1508 * Fixed same password authentication problem in the
1509 Authentication Payload handling routines in
1510 lib/silccore/silcauth.c.
1512 * Yet another password authentication problem fixed with
1513 channel password handling in silcd/command.c.
1515 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * If first character of string in silc_parse_userfqdn is '@'
1518 then do not parse it. Affected file is
1519 lib/silcutil/silcutil.c.
1521 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Fixed minor bug in IDENTIFY command reply sending, which
1524 caused various weird problems during JOIN when it was
1525 resolving names for users. Affected file silcd/command.c.
1527 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1529 * Fixed the IDENTIFY command reply sending to chech better valid
1530 clients. It was possible to send incomplete list of replies.
1531 Affected file silcd/command.c.
1533 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1535 * Added silc_client_command[s]_[un]register functions now to
1536 dynamically register the commands in client library. Removed
1537 the static table of commands. This allows the client library
1538 to call commands without causing the application to know about
1539 what commands library has called.
1541 Removed the INFO command reply kludge to detect when the command
1542 was called by library. Now library use its own command reply
1543 function for INFO command.
1545 Added function silc_client_command_call to call a command.
1546 Application can use it to call command, not access the structure
1549 Now all commands that are sent by the client library (not
1550 explicitly sent by application) use own command reply functions.
1552 Affected files around lib/silcclient/ and in
1553 irssi/src/silc/core/.
1555 * Fixed the WHOIS command reply sending to chech better valid
1556 clients. It was possible to send incomplete list of replies.
1558 Fixed the WHOIS and IDENTIFY to send the request to router
1559 if normal server did not do it and did not find any results.
1561 Affected file silcd/command.c.
1563 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Moved the internal data from SilcClient context into its
1566 own file, not accesible to application. Affected files
1567 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1568 and other files in client library.
1570 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Added doc/examples installation target in Makefile.am.pre.
1575 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1578 commands the found client entry will be removed from the
1579 cache, after notifying application about the error. Affected
1580 file lib/silcclient/command_reply.c.
1582 * Changed the /MSG to check for exact nickname user gave, and
1583 not let `nick' match `nick@host' if it is only one found. Now,
1584 user must type the exact nickname (like nick@host2) even if
1585 there are no more than one same nicks found. This is to avoid
1586 a possibility of sending nickname to wrong nickname since
1587 `nick' could match `nick@host'. Affected file is
1588 irssi/src/core/silc-servers.c.
1590 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Do not print "you are now server operator" or similar when
1593 giving /away command. Affected files are
1594 irssi/src/silc/core/client_ops.c, silc-servers.h.
1596 * Made the silc_server_command_pending_error_check to send
1597 the same command reply payload it received back to the
1598 original sender of the command. This way all arguments
1599 that was received by the server will be received by the
1600 client too. Affected file silcd/command.c.
1602 * Added the silc_idcache_add to return the created cache entry
1603 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1605 * Add global clients to expire if they are not on any channel.
1606 This is because normal server will never know if they signoff
1607 if they are not on any channel. The cache expiry will take
1608 case of these entries. This is done by normal servers only.
1609 The affected files are silcd/command_reply.c,
1610 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1612 * If server receives invalid ID notification for WHOIS or
1613 IDENTIFY and the ID exists in the lists, it is removed.
1614 Affected file silcd/command_reply.c.
1616 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1617 in client then client entry that it matches is searched and
1618 the nickname is printed on the screen for user. Affected
1619 file irssi/src/silc/core/client_ops.c.
1621 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Use cache entry expire time in the LIST command reply to
1624 purge old entries from the cache after the LIST command
1625 reply has been received. This way we don't have non-existent
1626 entries in the cache for too long. Affected file is
1627 silcd/command_reply.c.
1629 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * If we are normal server, and we've not resolved client info
1632 in WHOIS or IDENTIFY from router, and it is global client,
1633 we'll check whether it is on some channel. If it is not
1634 then we cannot be sure about its validity and will resolve it
1635 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1636 file silcd/command.c.
1638 * Search channel by name (if possible) rather than by ID
1639 in IDENTIFY command's command reply. Affected file is
1640 silcd/command_reply.c.
1642 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1645 Updated specs and implemented it. Affected file silcd/command.c,
1646 silcd/packet_send.c and silcd/packet_receive.c.
1648 * Implemented the <founder auth> payload handling in the JOIN
1649 command. If provided all conditions for channel joining
1650 except requirement to provide correct passphrase can be
1651 overrided by the channel founder. Updated the protocol specs.
1652 Affected file silcd/command.c.
1654 Added support for founder auth in JOIN command in client
1655 library. Fixed the parsing of the JOIN command now to support
1656 all options as they should be. The affected file is
1657 lib/silcclient/command.c.
1659 * Optimized the WHOIS and IDENTIFY commands to send the request
1660 to router only if it includes nicknames or other names. If
1661 they include only IDs then check the local cache first before
1662 routing. Affected file is silcd/command.c.
1664 * Added channels topic announcements. Affected file is
1665 silcd/packet_receive.c and silcd/server.c.
1667 * Fixed the silc_server_send_notify_topic_set to really destine
1668 the packet to channel. Affected file silcd/packet_send.c.
1670 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1671 library. Affected file lib/silcclient/client_notify.c.
1673 * Added UMODE announcements. Affected file silcd/server.c.
1675 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Memory leak fixes in:
1679 lib/silcutil/silcsockconn.c
1680 lib/silcske/silcske.c
1681 lib/silcske/groups.c
1683 lib/silccrypt/silcpkcs.c
1684 lib/silccore/silccommand.c
1685 lib/silccore/silcidcache.c
1690 * ROBOdoc documented the lib/silcske/groups.h file and a
1691 bit changed the interface for better.
1693 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1695 * Update the client entry context in the ID cache after
1696 nick change. Affected file lib/silcclient/command.c.
1697 Fixes the CUMODE command when regaining founder privileges,
1698 and a little WHOIS problem.
1700 * Fixed silc_net_gethostbyname to correctly call the
1701 inet_ntop. Affected file lib/silcutil/silcnet.c.
1703 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1705 * Added IPv6 support checking to the configure.in.pre, added
1706 also --enable-ipv6 option to override the check. Affected
1707 file configure.in.pre.
1709 * The silc_thread_create now calls the start function
1710 directly if threads support is not compiled in. Removes
1711 ugly #ifdef's from generic code. Affected files are
1712 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1714 * Added silc_net_gethostby[name/addr]_async to asynchronously
1715 resolve. Affected files are lib/silcutil/silcnet.[ch].
1717 * Added support for rendering IPv6 based server, client and
1718 channel IDs. Affected file lib/silcutil/silcutil.c.
1720 * Added support for creating IPv6 based server IDs. Affected
1721 file is silcd/serverid.c.
1723 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1725 * Added silc_net_gethostby[addr/name] into the
1726 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1727 routines. Added silc_net_is_ip[4/6]. Affected file is
1728 lib/silcutil/unix/silcunixnet.c. All routines that take
1729 address as argument now supports both IPv4 and IPv6 addresses.
1731 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1733 * Fixed LIST command reply sending in server. Affected file
1736 * Server now sends the kicker's client ID in the KICK notify
1737 to the kicked client. Affected file silcd/command.c.
1739 * The client library now parses the kickers client ID and
1740 UI displays it. Affected files lib/silcclient/client_notify.c
1741 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1743 * Made all payload parsing function prototypes consistent.
1744 They all take now const unsigned char * and uint32 pair as
1745 the payload data instead of SilcBuffer. Changes all around
1746 the source tree. Other unsigned char* -> const unsigned char*
1747 changes around the tree as well.
1749 * Optimized SFTP client and server packet sending not to
1750 allocate new buffer for each packet but to recycle the
1751 first allocated buffer. Affected files are
1752 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1754 * Optimized the SFTP client to use SilcList instead of
1755 SilcDList for requests, because it is faster. Affected file
1756 is lib/silcsftp/sftp_client.c.
1758 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1759 into lib/silccore/silcid.[ch].
1761 Renamed silcpayload.[ch] into silcargument.[ch].
1763 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * If client entry is deleted with active key agreement
1766 session, abort the session.
1768 The silc_client_abort_key_agreement now calls the completion
1769 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1771 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1774 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Don't use __restrict in older GCC's. Affected file is
1777 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1779 * silc_net_localhost now attempts to reverse lookup the
1780 IP/hostname. Affected file lib/silcutil/silcnet.c.
1782 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1783 command. It can be used to gain founder privileges at
1784 the same time when joining the channel.
1786 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1787 kicker's client ID as well. Updated protocol specs.
1789 Defined that the server must send SILC_COMMAND_IDENTIFY
1790 command reply with error status to client who sent
1791 private message with invalid client ID.
1793 Updated the protocol specification.
1795 * Added silc_server_send_command_reply to send any
1796 command reply. Affected file silcd/packet_send.[ch].
1798 * Added silc_id_payload_encode_data to encode ID payload
1799 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1801 * The server now send IDENTIFY command reply with error
1802 status if client ID in private message is invalid. Affected
1803 file silcd/packet_receive.c.
1805 * Save the server key file with server's IP address in
1806 the filename instead of hostname. The affected file is
1807 irssi/src/silc/core/client_ops.c.
1809 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1814 * Added libtool support for compiling shared objects in
1815 lib/silcsim. Affected file configure.in.pre and
1816 lib/silcsim/Makefile.am. Original patch by cras.
1818 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Pid file configuration, and server's config file fixes
1821 patch by toma. Updated CREDITS file.
1823 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Fixed silc_client_channel_message to not try to decrypt
1826 the message twice if it resolved the destination client
1827 information. This could cause of dropping one channel
1828 message. Affected file lib/silcclient/client_channel.c.
1830 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1833 lib/silcclient/client.c. This function is used when the SILC
1834 Client is run under some other scheduler, or event loop or
1835 main loop. On GUI applications, for example this may be
1836 desired to used to run the client under the GUI application's
1837 main loop. Typically the GUI application would register an
1838 idle task that calls this function multiple times in a second
1839 to quickly process the SILC specific data.
1841 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1843 * Fixed silc_server_drop() for dropping the supplementary
1844 groups as well, this could cause a security hole on some
1847 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1852 * Write PID file after dropping privileges. Added -F option
1853 to run server on foreground. A patch by debolaz.
1854 Affected files silcd/server.c, silcd/silcd.c.
1856 * Fixed MOTD to return the MOTD file server name. Affected
1857 file silcd/command.c.
1859 * Added INFO command reply handling to the Irssi SILC Client.
1860 Affected file irssi/src/silc/core/client_ops.c.
1862 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Fixed the silc_idcache_list_* routines to really support
1865 the dynamic list. Fixes a crash. Affected file is
1866 lib/silccore/silcidcache.c.
1868 * Fixed the LIST command reply to really call LIST command's
1869 pending callbacks. Affected file silcd/command_reply.c.
1871 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * Update conn->local_entry->nickname after giving NICK
1874 command. Affected file lib/silcclient/command.c.
1876 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1878 * Added the [pid] option to the silcd configuration file
1880 Affected files: serverconfig.[ch] and silcd.c
1882 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Save fingerprint in WHOIS command reply in server.
1885 Affected file silcd/command_reply.c.
1887 * Fixed NICK commands pending callback registration.
1888 Affected file lib/silcclient/command.c.
1890 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Use ++server->cmd_ident when sending commands in server,
1893 instead of random number. Affected file silcd/command.c.
1895 * Fixed GETKEY command reply to call actually GETKEY pending
1896 command callbacks. Affected file silcd/command_reply.c.
1898 * A bit stricter check for nicknames. Check for same nickname
1899 in NICK command also. Affected file silcd/command.c.
1901 * Do not call INFO command everytime client ID changes, only
1902 during first connecting. Affected file lib/silcclient/client.c.
1904 * Set the new nickname only after successful command reply for
1905 NICK command is returned by server. Affected file
1906 lib/silcclient/command.c.
1908 * Remove nicknames from nicklist during server_signoff notify.
1909 Should fix /NAMES bit more. The affected file is
1910 irssi/src/silc/core/silc-channels.c.
1912 * Added `fingerprint' field to the SilcIDListData in the
1913 silcd/idlist.h to hold the fingerprint of the client's
1916 Send the fingerprint of the client's public key in WHOIS
1919 Affected files silcd/command.c, and silcd/idlist.[ch].
1921 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1922 create fingerprint from given data.
1924 * Show the fingerprint of the client's public key in WHOIS.
1925 Affected files irssi/src/module-formats.[ch] and
1926 irssi/src/silc/core/client_ops.c.
1928 * Format the multiple same nicknames also during JOIN and
1929 NICK_CHANGE notifys. Affected file is
1930 lib/silcclient/client_notify.c.
1932 * Do not print error on screen for invalid private message
1933 payload since it can come if someone is sending private
1934 messages with wrong key. Affected file
1935 lib/silccore/silcprivate.c.
1937 * Fixed multiple concurrent /PING crash. Affected file
1938 lib/silcclient/command.c.
1940 * Changed the wrong ID encoding. All IP addresses must be
1941 in MSB first order in encoded format. They were encoded
1942 wrong and was in LSB format. Affected files are
1943 silcd/serverid.c, lib/silcutil/silcutil.c.
1945 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1947 * Call the `connect' client operation through the scheduler
1948 in case of error. Affected file lib/silcclient/client.c.
1950 * Call the `failure' client operation even if the error
1951 occurred locally during a protocol. Affected file is
1952 lib/silcclient/protocol.c.
1954 * Added support of sending LIST command to router from normal
1955 server. This way normal server can get list of all channels
1956 in the network too. Fixed the channel list sending in the
1957 server too. Affected files are silcd/command.c, and
1958 silcd/command_reply.[ch].
1960 * Added silc_server_update_channels_by_server and
1961 silc_server_remove_channels_by_server. They are used during
1962 disconnection of primary router and in backup router protocol.
1963 Affected file silcd/server_util.[ch], silcd/server.c and
1964 silcd/server_backup.c.
1966 * Fixed channel adding to global list in IDENTIFY command
1967 reply in server. Affected file silcd/command_reply.c.
1969 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * If the incoming packet type is REKEY or REKEY_DONE process
1972 that packet always synchronously. Fixes yet another MAC
1973 failed error on slow (dialup) connections. Affected file
1974 lib/silcclient/client.c and silcd/server.c.
1976 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Call check_version SKE callback for initiator too. Affected
1979 file lib/silcske/silcske.c.
1981 * Implemented fix for security hole found in the SKE that was
1982 fixed in the specification few days back; the initiator's
1983 public key is now added to the HASH value computation.
1984 Added backwards support for the old way of doing it too, for
1985 old clients and old servers. Affected file is
1986 lib/silcske/silcske.c.
1988 * Enabled mutual authentication by default in SKE. If initiator
1989 is not providing mutual authentication the responder will
1990 force it. This will provide the proof of posession of the
1991 private key for responder. The affected files are
1992 lib/silcclient/protocol.c and silcd/protocol.c.
1994 * Do not cache anymore the server's public key during SKE.
1995 We do mutual authentication so the proof of posession of
1996 private key is done, and if the server is authenticated in
1997 conn auth protocol with public key we must have the public
1998 key already. Affected file silcd/protocol.c.
2000 * Added new global debug variable: silc_debug_hexdump. If
2001 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2002 file lib/silcutil/silclog.[ch].
2004 * Fixed compilation warning due to char * -> const char *.
2005 Affected files lib/silcutil/silcnet.h, and
2006 lib/silccore/silcauth.[ch].
2008 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Fixed CMODE command when new channel key was created. If
2011 the creation failed the old key was removed. Next time giving
2012 same command would crash the server since the old key was
2013 freed already. Affected file silcd/command.c.
2015 * Fixed the silc_server_announce_get_channels to not crash
2016 on reconnect. Affected file silcd/server.c.
2018 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Added silc_log_set_debug_string function to set a regex
2021 string to match for debug output. Only the function names,
2022 or filenames matching the given debug string is actually
2023 printed. This way it is possible to filter out those debug
2024 strings that user is not interested in.
2026 Fixed a bug in silc_string_regexify.
2028 Affected files lib/silcutil/silclog.[ch], and
2029 lib/silcutil/unix/silcunixutil.c.
2031 * Changed the -d options in both server and Irssi SILC client
2032 to take the debug string as argument. Affected files
2033 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2035 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Added silc_hash_babbleprint to create a Bubble Babble
2038 Encoded fingerprint. The encoding is developed by Antti
2039 Huima (draft-huima-babble-01.txt), and it creates human
2040 readable strings out of binary data. Affected file
2041 lib/silccrypt/silchash.[ch].
2043 * Print the babble print now in addition of fingerprint as well
2044 in Irssi SILC client. Affected files are
2045 irssi/src/fe-common/silc/module-formats.[ch],
2046 irssi/src/fe-common/silc/core/client_ops.c.
2048 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Fixed a security problem found in SKE. The initiator's
2051 public key too is now added to the HASH hash value creation
2052 which is signed by the responder to create the SIGN value.
2053 This will prevent anyone in the middle to lie to the responder
2054 about the initiator's public key. If this is done now, the
2055 man in the middle will get caught. Updated the protocol
2058 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Better installation directory handling. Configure module
2061 paths and other paths automatically to example_silc* files
2062 in doc/. A patch by toma.
2064 * Fixed compiler warning from MPI library, and from SILC RNG.
2067 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2068 It can be configured with ./configure. A patch by toma.
2070 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Find correct make to use in prepare-clean. A patch by
2073 toma. Affected file prepare-clean.
2075 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2077 * Added irssi variables use_auto_addr, auto_bind_ip,
2078 auto_bind_port and auto_public_ip.
2080 * Changed the interface for silc_client_send_key_agreement
2081 in lib/silcclient/silcapi.h
2085 irssi/src/silc/core/silc-core.c
2087 lib/silcclient/silcapi.h
2088 irssi/src/silc/core/silc-channels.c
2089 lib/silcclient/client_keyagr.c
2092 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Added silc_pkcs_public_key_compare to compare two
2095 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2097 * Check that the client who set the founder mode on the
2098 channel is the same client that is giving the founder
2099 mode to itself. It is done by comparing the saved public
2100 key (it is saved even in the authentication is passphrase).
2101 Affected file silcd/command.c.
2103 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Do not process packet for disconnected socket connection.
2106 Affected file lib/silccore/silcpacket.c.
2108 * Process the DISCONNECT packet through scheduler in the
2109 client library. Affected file lib/silcclient/client.c.
2111 * Fixed the silc_client_packet_parse to not to increase
2112 the packet sequence number if the conn->sock and the
2113 current socket connection is not same. This can happen
2114 for example during key agreement when the conn includes
2115 multiple socket connections (listeners). Affected file
2116 lib/silcclient/client.c.
2118 * The sender of the file transfer request now provides also
2119 the pointer (listener) for the key exchange protocol. If
2120 the listener cannot be created then it sends empty key
2121 agreement and lets the receiver provide the listener.
2123 Added `local_ip' and `local_port' arguments to the
2124 silc_client_file_send. If they are provided they are used,
2125 if not then it will attempt to find local IP address, if
2126 not found or bind fails then the remote client will provide
2129 Affected files are lib/silcclient/client_ftp.c and
2130 lib/silcclient/silcapi.h.

2205 preserve the WHOWAS info for the client. Affected file
2206 silcd/server_util.c.
2208 * Fixed SERVER_SIGNOFF notify handling in the server. The
2209 server is now able to process incoming SERVER_SIGNOFF notify
2210 for a server that it doesn't even know about. It will remove
2211 the clients provided in the notify. Affected file
2212 silcd/packet_receive.c.
2214 * Check for partial packet in data queue after every packet that
2215 was found from the queue. Return and wait for more data if
2216 there is partial data in queue. Affected file is

2234 irssi/src/fe-common/silc/module-formats.[ch].
2236 * Wrote a help file for FILE command.
2238 * Added silc_rng_global_get_byte_fast to get not-so-secure
2239 random data as fast as possible. Random data is read from
2240 /dev/urandom if available and from the SILC RNG if not
2241 available. It is used in padding generation. Affected file
2242 lib/silccrypt/silcrng.[ch].
2244 * All packets in client library are now processed synchronously.
2245 Optimized packet processing a lot. Affected file
2246 lib/silcclient/client.c.

2257 * Assure that silc_client_notify_by_server_resolve does not
2258 resolve the client information multiple times. If it cannot
2259 be found by the first it cannot be found at all. Affected
2260 file lib/silcclient/client_notify.c.
2262 * Fixed WHOWAS command reply calling. Affected file
2263 lib/silcclient/command_reply.c.
2265 * Removed all references to silc_idlist_get_client from the
2266 Irssi SILC client since that call is internal call used by
2267 the library. The Irssi SILC client will use now client
2268 retrieval functions found in silcapi.h.
2270 * Fixed a bug in resolving nickname info before sending
2271 private message. It used freed memory. Affected file
2272 irssi/src/silc/core/silc-servers.c.
2274 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Assure my_channels statistics cannot go negative in server.
2277 Affected files silcd/server.c, silcd/server_util.c.

2293 * Added silc_net_localip to return local host's IP address.
2294 Affected file lib/silcutil/silcnet.[ch].
2296 * If key exchange or rekey protocol is active for a connection
2297 parse all packets syncronously since there might be packets
2298 in packet queue that we are not able to process without first
2299 processing packets before them. Affected file silcd/server,
2300 lib/silcclient/client.c.
2302 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2303 whether library should continue processing the packet.
2304 Affected file lib/silccore/silcpacket.h.

2350 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2351 is incomplete and is being resolved, it won't be resolved
2354 Make sure also that USERS command reply does not resolve
2355 twice information. Affected file is
2356 lib/silcclient/command_reply.c.
2358 Make sure that silc_client_get_clients_by_list does not
2359 resolve twice same information.
2361 * Check for valid client->id in the silc_server_free_client_data.
2362 Affected file silcd/server.c.
2364 * Fixed /GETKEY nick@server not to crash if the server entry
2365 is not found. Affected file lib/silcclient/command.c.
2367 * Fixed the silc_server_check_cmode_rights to check the
2368 requested modes correctly. Affected file silcd/command.c.

2373 Affected file silcd/command.c.
2375 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Call the silc_server_udpate_servers_by_server in the
2378 primary router that comes back online in the backup resuming
2379 protocol. Otherwise it routes packets wrong. Affected file
2380 silcd/server_util.[ch], silcd/server_backup.c.
2382 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2385 lib/silcutil/silcbuffmt.[ch].
2387 * Redefined the SILC packet header to include the padding
2388 length. Affected file lib/silccore/silcpacket.[ch].
2390 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2391 length for maximum padding up to 128 bytes). Affected
2392 file lib/silccore/silcpacket.h.
2394 * Removed all backwards support for old 0.5.x MAC thingies.
2395 The SILC packet header change makes it impossible to be
2396 backwards compatible.
2398 * Send the ENDING packet with timeout in the backup resuming
2399 protocol. This is to assure that all routers has connected
2400 to the primary router. Affected file silcd/server_backup.c.
2402 * Changed the RNG to take the first IV from random data. It
2403 used to take it from zero actually. Changed the RNG also
2404 to use /dev/urandom during session. /dev/random is used
2405 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2407 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Changed the SILC packet header to have the first two bytes
2410 (the packet length) encrypted. Affected files aroung the
2411 code tree, lib/silccore/silcpacket.[ch]. Removed the
2412 SilcPacketCheckDecrypt callback. It is not needed anymore
2413 since the silc_packet_receive_process will determine now
2414 whether the packet is normal or special.
2416 * Implemented the unidirectional MAC keys. Affected files
2417 lib/silcske/silcske.c, silcd/protocol.c and
2418 lib/silcclient/protocol.c.
2420 * Implemented the packet sequence number to the MAC computation.
2421 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2422 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2423 lib/silcclient/protocol.c.
2425 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Allow backup router to announce servers. All servers
2428 announced by backup router are added to the global list
2429 automatically. Update hte server's socket to our primary
2430 router also when backup router announces a server.
2431 Affected file silcd/packet_receive.c.
2433 * Do not update the client->router in the function
2434 silc_server_udpate_clients_by_server if the client is on
2435 global list. We might fail to find any specific server
2436 for locally connected clients and local cell clients. They
2437 should still use the `from' and not `to' as client->router.
2438 This fixes backup router resuming protocol. Affected file
2439 silcd/server_util.c.
2441 * Decrease channel statistics count only if the channel
2442 deletion worked. Affected files are silcd/server.c and
2443 silcd/server_util.c.
2445 * Added silc_server_update_servers_by_server to update origin
2446 of all server entries. Used during backup router protocol.
2447 Affected files silcd/server_util.[ch], silcd/server.c. and
2448 silcd/backup_router.c.
2450 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2451 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2452 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2453 lib/silccrypt/silchmac.c.
2455 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Assure that router cannot reroute the same channel message
2458 to the sender. Affected file silcd/packet_receive.c.
2460 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Made better checks that the channel message is not sent
2463 to the router it came from. Affected file is
2464 silcd/packet_send.c. Fixed memory leak too.
2466 * Announce informations for incoming router connection, but
2467 only after checking if it is replaced by backup router.
2468 Affected file silcd/packet_receive.c.
2470 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Fixed the backup resuming protocol to work in multiple
2473 router environment. Affected file silcd/server_backup.c.
2475 * Route packet only to one router in the function
2476 silc_server_packet_send_to_channel. Affected file is
2477 silcd/packet_send.c.
2479 * Fixed silc_server_send_notify_dest to set the broadcast
2480 flag. Fixed the silc_server_send_notify_topic to actually
2481 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2482 Affected file silcd/packet_send.c.
2484 * Changed the SFTP Filesystem interface. Changed the
2485 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2486 the filesystem operation function. The SilcSFTPFilesystem
2487 is now a context that is allocated by all filesystem allocation
2488 functions and it already includes the operations structure
2489 and filesystem specific context. It is given as argument
2490 now to the silc_sftp_server_start. This made the interface
2491 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2492 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2494 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Changed the backup router adding and getting interfaces
2497 in the server. The router that will be replaced by the
2498 specified backup router is now sent as argument. Affected
2499 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2502 * Added silc_net_addr2bin_ne to return the binary form of
2503 the IP address in network byte order. Affected files
2504 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2506 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Check for existing server ID in silc_server_new_server
2509 and in silc_server_connect_to_router_final and remove the
2510 old entry if it exists. Affected file silcd/packet_receive.c,
2513 * Send the channel message always to only one router, either
2514 in upstream or downstream. Affected file is
2515 silcd/packet_send.c.
2517 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Wrote the definition of the backup resuming protocol to the
2520 protocol specification.
2522 * Removed one redundant channel key generation from normal
2523 server during joining procedure. Removed one redundant
2524 channel key sending from server to router during joining
2525 procedure. Affected file silcd/command.c.
2527 * Made minor bugfixes to the backup router resuming protocol.
2528 Affected file silcd/server_backup.c, server.c.
2530 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Added --disable-asm configuration option. Affected files
2533 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2536 * Implemented the backup resuming protocol that is used to
2537 resume the primary router position in the cell after the
2538 primary router comes back online. Affected files
2539 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2540 and silcd/server_util.[ch].
2542 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Sleep two (2) seconds after sending QUIT command to server.
2545 Affected file lib/silcclient/command.c.
2547 * Assure that if outgoing data buffer is pending do not force
2548 send any data. Affected file silcd/packet_send.c.
2550 * Assure that if outgoing data buffer is pending do not force
2551 send any data. Affected file lib/silcclient/client.c.
2553 * Implemented the backup router support when the primary router
2554 goes down. The servers and routers can now use the backup
2555 router as new primary router without loosing connectivity.
2557 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2560 in the server to indicate disabled entry. All data read
2561 from the connection will be ignored and no data is sent
2562 for entry that is disabled. Affected files are
2563 silcd/idlist.h, silcd/server.c.
2565 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Created SFTP client and server test programs in the
2568 lib/silcsftp/tests directory.
2570 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Implemented memory filesystem (virtual filesystem) for
2573 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2576 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Implemented the SFTP (SSH File Transfer Protocol) to the
2579 lib/silcsftp. It includes SFTP client and SFTP server
2582 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Moved lib/silccore/silcprotocol.[ch] to the
2585 lib/silcutil library.
2587 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2588 take variable argument list pointer as argument. Affected
2589 file lib/silcutil/silcbuffmt.[ch].
2591 * Added silc_buffer_set function that is used to set data
2592 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2593 Affected file lib/silcutil/silcbuffer.h.
2595 * Changed various routines in the core library to use the new
2596 silc_buffer_set instead of allocating new buffer only for
2599 * Added 64-bit value formatting and unformatting support to the
2600 silc_buffer_[un]format routines. Affected file is
2601 lib/silcutil/silcbuffmt.[ch].
2603 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2604 to includes/bitmove.h.
2606 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Fixed channel user mode saving in client library. Affected
2609 file lib/silcclient/command[_reply].c.
2611 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2613 * Defined the file transfer to the SILC Protocol. Added
2614 new packet type SILC_PACKET_FTP and defined File Transfer
2615 Payload. The mandatory file transfer protocol is SFTP
2616 (SSH File Transfer Protocol). Affected file in addition
2617 of the internet draft is lib/silccore/silcpacket.h.
2619 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2620 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2621 is used as part of backup router protocol when the primary
2622 router of the cell is back online and wishes to resume
2623 the position as primary router.
2625 * Redefined the MAC generation keys in the protocol. The
2626 same key is not used anymore in both direction. Both
2627 direction will now use different keys for sending and
2628 receiving. This fixes a potential security flaw. This
2629 change causes incompatibilities in the protocol.
2631 * Redefined also the MAC computation from the packet.
2632 An packet sequence number is now added to the MAC
2633 computation. This prevents possible replay attacks against
2634 the protocol. This change too causes incompatibilities
2637 Added `sequence' field to the SilcPacketContext to hold
2638 the current sequence number for the packet.
2640 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Added `created' field to the SilcIDListData in the file
2643 silcd/idlist.h to indicate the time when the entry was
2646 * Added `created' field to the SilcChannelEntry too. Affected
2647 file silcd/idlist.h.
2649 * Added `creation_time' aguments to all the announcement functions
2650 in the server. If it is provided then only the entries that
2651 was created after the provided time frame are actually
2652 announced. Affected file silcd/server.[ch].
2654 * The protocol says that the Channel ID's IP address must be
2655 based on the router's IP address. Added check for this in
2656 the silc_server_new_channel when processing incoming New Channel
2657 Payload. Affected file silcd/packet_receive.c.
2659 * Print out the correct version with --version in SILC client.
2660 Affected file irssi/src/silc/core/silc-core.c.
2662 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Fixed WHOWAS command to check for completnes of the client
2665 entry always, not just when the command is coming from client.
2666 Affected file silcd/command.c.
2668 * Added new function silc_server_packet_queue_purge to purge the
2669 outgoing data queue to the network. After the function returns
2670 it is guaranteed that the outgoing packet queue is empty.
2671 Affected file silcd/packet_send.[ch].
2673 * Purge the outgoing packet queue in the rekey protocol's final
2674 callback to assure that all rekey packets go to the network
2675 before quitting the protocol. Affected file silcd/server.c.
2677 * Added silc_client_packet_queue_parse as similar function as
2678 in server to the client library. The affected file is
2679 lib/silcclient/client.c.
2681 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Splitted silcd/server.c and created silcd/server_util.[ch]
2684 for utility functions.
2686 * Added new socket flag SILC_SF_DISABLED to indicate that the
2687 connection is open but nothing can be sent to or received from
2688 the connection. Affected file lib/silcutil/silsockconn.[ch].
2689 The checking for disabled socket is checked in the low level
2690 silc_socket_write and silc_socket_read functions.
2692 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * Allow only nicknames and channel names that fits into the
2695 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2697 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2699 * When processing JOIN command reply in server check that if
2700 the channel exists in our global list we'll move it the local
2701 list. Affected file silcd/command_reply.c.
2703 * Fixed the check whether client is joined on the channel already
2704 in JOIN command. Affected file lib/silcclient/command.c.
2706 * Fixed the JOIN command reply to check whether the channel
2707 already exists. Affected file lib/silcclient/command_reply.c.
2709 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Added silc_ske_status_string to map the SKE error numbers
2712 to readable strings. The affected files are
2713 lib/silcske/silcske[_status].[ch].
2715 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Do not show the private channels on the WHOIS channel list
2718 as it is not allowed by the protocol. The affected file is
2721 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Assure that the packet length digged from the actual packet
2724 is something sensible in the silc_packet_decrypt_rest_special
2725 in lib/silccrypt/silcpacket.c.
2727 * Free and NULL the allocated pointer in silc_hmac_alloc if
2728 the HMAC allocation fails. The affected file is
2729 lib/silccrypt/silchmac.c.
2731 * Print the selected security properties to the log files in
2732 the server. Affected file silcd/protocol.c.
2734 * Add SKE's reference counter even if calling the completion
2735 callback manually. Otherwise it goes negative, although it
2736 does not cause any problems. The affected file is
2737 lib/silcske/silcske.c.
2739 * Remove the client entry with short timeout after giving the
2740 KILL command. Affected file lib/silcclient/command.c.
2742 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2743 case all found clients are already disconnected (WHOWAS would
2744 found them) in the server. Affected file silcd/command.c.
2746 * Update the last_receive (time of last data received) to be
2747 updated only when received private or channel message so that
2748 the idle time showed in WHOIS makes more sense.
2750 * Added boolean field `valid' in to the SilcClientEntry in the
2751 client library to indicate whether the entry is valid or not.
2752 This fixes the nickname change bug on channel when changing
2753 the nickname to be same than the old (like nick to Nick) the
2754 nickname formatter doesn't set the new nick anymore to Nick@host.
2755 Affected file lib/silcclient/idlist.[ch].
2757 * Now actually fixed the nickname changing on disconnection.
2758 Added new function silc_change_nick to the Irssi SILC Client.
2759 Affected file irssi/src/silc/core/client_ops.c,
2760 irssi/src/silc/core/silc-nicklist.[ch].
2762 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Check that the public key exists in the GETKEY command before
2765 trying to encode it. Affected file silcd/command.c.
2767 * Print some notifications on received public keys with GETKEY
2768 command in the Irssi SILC Client. Affected files are
2769 irssi/src/fe-common/silc/module-formats.[ch],
2770 irssi/src/silc/core/client_ops.c.
2772 * Use IDENTIFY command to resolve the server information in the
2773 GETKEY command instead of INFO command. Affected file
2774 lib/silcclient/command.c.
2776 * All command reply functions in the client library now calls
2777 the pending command reply callbacks even if an error has
2778 occurred. The server has done this a long time and now it was
2779 time to move the client library to this as well. Now all
2780 errors can be delivered back to the pending command reply
2781 callbacks if necessary. Affected files are
2782 lib/silcclient/command[_reply].[ch].
2784 * Change the nickname on disconnection back to the username
2785 because in reconnect the server will enforce it to it anyway.
2786 Affected file irssi/src/silc/core/silc-servers.c.
2788 * Fixed a config file parsing bug in the Irssi SILC client.
2789 Affected file irssi/src/silc/core/clientconfig.c.
2791 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * When printing the channel mode on JOIN, verify that the
2794 channel key and channel's HMAC are valid. Affected file
2795 irssi/src/silc/core/client_ops.c.
2797 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2800 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2801 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2803 * Removed channel key rekey task deleting from the function
2804 silc_server_save_channel_key. Affected file silcd/server.c.
2805 Added explicit timeout task context instead that is used to
2806 delete the task if we are registering a new task before the
2807 new task has elapsed.
2809 * When channel key rekey occurs the client library now saves
2810 the old channel key for a short period of time (10 seconds) and
2811 is able to use it in case some is still sending channel
2812 messages encrypted with the old key after the rekey. Affected
2813 file lib/silcclient/[idlist.h|client_channel.c].
2815 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Added check to the silc_server_new_id_real to not accept
2818 new ID if it is the sender's own ID. Affected file is
2819 silcd/packet_receive.c.
2821 * Assure that we do not announce ourself or the one we've
2822 sending our announcements when we're router and are announcing
2823 servers to our primary router. Affected file silcd/server.c.
2825 * Fixed silc_server_command_identify_check_client to assemble
2826 correct WHOIS packet. It send corrupted WHOIS packet and
2827 caused problem with router to router connections. Affected
2828 file silcd/command.c.
2830 Fixed also silc_server_command_whois_check the same way
2831 as for the IDENTIFY command.
2833 * Added new SilcIDListStatus to the server in the SilcIDListData
2834 structure. The status now includes the current status of
2835 the entry (like registered, resolved etc.). Affected file
2836 silcd/idlist.[ch]. Defined a bunch of different status types
2837 as well. This replaced the old boolean registered field as well.
2839 Added resolve_cmd_ident field to the SilcClientEntry structure
2840 too so that if the entry is for example being resolved so
2841 another command may attach to the same pending command reply
2842 without requiring to resolve the same entry again. This concept
2843 should optimize the WHOIS and the IDENTIFY resolving under
2844 heavy load by taking away unnecessary resolving for entries
2845 that are being resolved already.
2847 Added support for adding multiple pending commands for one
2848 command idenfier. Affected file silcd/command[_reply].[ch].
2850 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2851 before deleting the data. Otherwise the hash table will have
2852 freed data in comparison functions. Affected file is
2853 silcd/command_reply.c.
2855 * Fixed silc_idlist_replace_client_id to add the new entry to
2856 the cache with NULL nickname. Otherwise there will be invalid
2857 memory as the nickname after the nickname is freed. Affected
2858 file silcd/packet_receive.c.
2860 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2861 saved into wrong slots because the previous number of entries
2862 was not taken into account. Affected file silcd/idlist.c.
2863 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2865 * If we are router and we receive JOIN notify to a channel that
2866 does not have any users then notified client is marked as the
2867 channel founder, as it is it. The affected file is
2868 silcd/packet_receive.c
2870 * Added to the extended hash table API's table_del_*ext functions
2871 the destructor as argument too, so that the caller can decide
2872 which destructor to use or whether to use destructor at all.
2873 Affected file lib/silcutil/silchashtable.[ch].
2875 * Fixed ID Cache purging. It actually deleted the entries from
2876 the hash table after the data was freed. The hash table ended
2877 up comparing freed memory. The affected file is
2878 lib/silccore/silcidcache.c.
2880 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Fixed Irssi SILC client's KILL command's HELP syntax.
2884 * The USERS command now resolves the detailed user information
2885 if the userinfo field is missing. Affected file is
2886 lib/silcclient/command_reply.c.
2888 * Do not print error in silc_file_read if the read file does
2889 not exist. Just silently return NULL. Affected file is
2890 lib/silcutil/silcutil.c.
2892 * Fixed the silc_log_output to not wine about NULL filename
2893 and to not create some bogus " " filename. Affected file is
2894 lib/silcutil/silclog.c.
2896 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Fixed various printing bugs on the user interface in the
2899 Irssi SILC Client. Minor changes that were forgotten from
2902 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Fixed the configure.in.pre and the compilation and distribution
2905 environment to support the new autoconf 2.52. That version is
2906 now required to compile the CVS trunk.
2908 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2911 to generally parse user@fqdn format strings. Affected file
2912 lib/silcutil/silcutil.c.
2914 * Added nickname_format and nickname_force_format fields to the
2915 SilcClientParams structure. The first one defines the format
2916 for the nicknames that the library will enforce if the receives
2917 multiple same nicknames. The second one is boolean value and
2918 can be used to force the library to always enforce the format
2919 to the nicknames regardles whether there are multiple nicknames
2920 or not. This configurable formatting was employed to flexibly
2921 support accessing multiple nicknames from the user interface.
2922 The userinterface can now set the nicknames to what ever format
2923 they prefer. Affected file lib/silcclient/silcapi.h.
2925 Added function silc_client_nickname_format to the file
2926 lib/silcclient/idlist.c. It performs the nickname formatting.
2928 Added new field `hostname´ to the SilcClientEntry context.
2929 It holds the hostname of the client. Affected file is
2930 lib/silcclient/idlist.h.
2932 * Irssi SILC Client sets the nicknames in nick@hostn format.
2933 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2934 irssi/src/silc/core/silc-core.c.
2936 The WHOIS printing now also shows both the real nickname and
2937 the formatted nickname so that user knows how to access the
2938 user if there are multiple same nicknames cached. Affected
2939 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2940 printing formatting too to take the hostname now as a separate
2941 argument. The Affected file is
2942 irssi/src/fe-common/silc/modules-formats.[ch].
2944 * Changed the silc_client_get_clients_local to accept the formatted
2945 nickname as argument. It accepts the real nickname too but the
2946 formatted nickname can be used to find the true entry from
2947 multiple entries. Affected file lib/silcclient/silcapi.h and
2948 lib/silcclient/idlist.c.
2950 * Added nickname_format_parse field to the SilcClientParams.
2951 It is a callback function provided by the application to parse
2952 the nickname out of the formatted nickname string. The library
2953 calls it to get the nickname from the formatted string. Since
2954 the application generally knows better the format of the nickname
2955 string it parses it instead of the library, even though library
2956 encodes the formatted string. If the callback function is not
2957 provided then the library will use the string as is. The
2958 affected file is lib/silcclient/silcapi.h.
2960 * All the nickname strings passed to the client library in
2961 commands are now expected to be formatted nickname strings.
2962 If the command does not support the formatted nickname string
2963 it will assume that the sent string is the actual nickname.
2964 Affected file lib/silcclient/command.c.
2966 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Added public key authentication support to OPER and SILCOPER
2969 commands in the client library. Affected file is
2970 lib/silcclient/command.c.
2972 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Changed the get_auth_methdod client operation to be asynchronous.
2975 It can be async if the application resolves the authentication
2976 method from the server during the negotiation. Added new
2977 SilcGetAuthMeth completion callback that the application will
2978 call after resolving the authentication method.
2980 Added function silc_client_request_authentication_method that
2981 the application can use to resolve the authentication method
2982 from the server. Added also SilcConnectionAuthRequest callback
2983 that the library will call after the server has replied. The
2984 application can call this function if it does not know the
2985 current authentication method.
2987 Affected files are lib/silcclient/client.c and
2988 lib/silcclient/silcapi.h.
2990 * The Irssi SILC client now automatically resolves the authentication
2991 method incase any configuration information is not present (and
2992 currently there never is). The affected file is
2993 irssi/src/silc/core/client_ops.c.
2995 * Fixed public key authentication from the client library.
2996 Affected file lib/silcclient/protocol.c. Changed also the
2997 protocol specification about the public key authentication in
2998 the connection authentication protocol. The actual data to be
2999 signed is now computed with a hash function before signing.
3001 * Fixed the public key authentication from the server as well.
3002 Affected file silcd/protocol.c.
3004 * Removed the mlock()'s from the memory allocation routines.
3005 Affected file lib/silcutil/silcmemory.c. The ./configure does
3006 not check anymore for the mlock(). Affected file is
3009 * Fixed USERS command in server to allow the execution of the
3010 command for private and secret channels if the client sending
3011 the command is on the channel. Affected file silcd/command.c.
3013 * Fixed silc_client_get_clients_local to return the clients
3014 count correctly. It could return wrong value. Affected file
3015 lib/silcclient/idlist.c.
3017 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3020 types. The assembler optimizations seemed not to like 64-bit
3021 data types. The assmebler optimizations thus are now enabled
3022 also for BSD systems as opposed to only enable them for Linux.
3024 * Do not check for threads at all on BSD systems. Affected
3025 file configure.in.pre.
3027 * Removed -n and -h options from the Irssi SILC Client since
3028 they are not used in silc.
3030 * Fixed the prime generation to assure that the first digit
3031 of the generated random number is not zero since our conversion
3032 routines does not like number strings that starts with zero
3033 digit. If zero digit is seen the random number is regenerated.
3034 This caused some corrupted RSA keys when the zero first digit
3035 was met. Affected file lib/silcmath/silcprimegen.c.
3037 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * Fixed WIN32 configuration in the ./configure script.
3040 Fixed to include xti.h on environments that has it.
3041 Patches by Carsten Ilchmann and andrew.
3043 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Changed the silc_id_create_client_id to be collision
3046 resistant. It is now assured that there cannot be created
3047 two same client ID's. I suspect that some weird bugs in
3048 the server were actually caused by duplicate Client IDs.
3049 Affected file silcd/serverid.[ch]. A router receiving
3050 new ID now also assures and informs the sending server
3051 if the ID caused collision.
3053 * Changed the silc_id_create_channel_id to also assure that
3054 there are no collisions.
3056 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3058 * Statement about ignoring the Mutual Authentication flag when
3059 performing rekey with PFS was a bit misleading. It is ignored
3060 if it was set in the initial negotiation, it cannot be even
3061 set in the rekey. Fixed in the ke-auth draft. Started the
3062 new versions of the protocol drafts in the doc/.
3064 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Fixed a bug in silc_client_command_identify_save when saving
3067 new channel information. The channel name was no duplicated
3068 and caused crash on exit. Affected file is
3069 lib/silcclient/command_reply.c.
3071 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Fixed the getkey command handling in the server. Send just
3074 empty OK reply to the sender if the key could not be fetched
3075 (but everything else was ok, like the key just was not available).
3076 Changed the public key parameter to optional in the protocol
3077 specs so that empty OK reply can be sent. Affected file
3080 Added a message to Irssi SILC client to tell to user if the
3081 server did not return a public key.
3083 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * Fixed a channel key regeneration bug. It registered new
3086 timeout tasks exponentially until all system resources were
3087 used. Affected file silcd/server.c.
3089 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3091 * Added the SILC Document generator to the scripts/silcdoc.
3092 It can be used to generate the Toolkit Reference Manual out
3093 of the source tree. Internally it will also use the RoboDoc
3094 generator now imported in util/robodoc.
3096 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Added couple of return's in rekey protocol if error orccurred
3099 during the protocol. The execution must be terminated.
3100 Affected file silcd/protocol.c. Also, terminate the protocol
3101 always with timeout.
3103 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3105 * The client's Client ID was created initally from the wrong
3106 nickname (it could have been in format nick@host) in the
3107 silc_server_new_client. Affected file silcd/packet_receive.c
3109 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Added some SILC_LOG_ERROR's to various error conditions
3112 if client could not be added to ID cache. Affected files
3113 silcd/packet_receive.c and silcd/server.c.
3115 * When client's sock->user_data is freed, NULL also the
3116 client->router and client->connection pointers. Added check
3117 for these pointers being NULL to various places around the
3118 code. Affected file silcd/server.c.
3120 * Added client->data.registered == TRUE checks to various
3121 places around the code to assure that unregistered client's
3122 are not handled when it is not allowed. Affected file
3125 * Added `bool registered' fields to all
3126 silc_idlist_[server|client]_get_* routines to indicate whether
3127 the fetched client needs to be registered or not. Affected
3128 file silcd/idlist.[ch].
3130 * Add your own entry as registered to the ID cache in the
3131 server. Affected file server.c.
3133 * Fixed a bug in silc_server_new_server. The SilcServer was
3134 set as the new server's context instead of SilcServerEntry.
3135 This naturally caused some weird bugs.
3137 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Do not delete the channel rekey task when adding it
3140 for in silc_server_create_channel_key.
3142 * Changed the silc_server_create_channel_key to return
3143 TRUE or FALSE to indicate the success of the channel key
3146 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3148 * Fixed MSVC++ project files and added missing files to
3149 Makefiles under win32/.
3151 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Do not add TCP_NODELAY flag if the operating system
3154 does not have it defined. Affected files are
3155 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3157 * Fixed buffer overflow from Irssi SILC Client. Affected
3158 file irssi/src/fe-common/core/themes.c.
3160 * Fixed double free in client library in the file
3161 lib/silcclient/client.c when disconnecting from server.
3163 * Applied double free patch from cras to Irssi SILC client.
3164 Affected files irssi/src/core/[modules/expandos].c
3166 * Fixed the disconnection handling to Irssi SILC Client.
3167 The application must call silc_client_close_connection
3168 in ops->connect client operation in case of failure of
3169 the connection. Affected file is
3170 irssi/src/silc/core/client_ops.c.
3172 * Do not set sock->protocol to NULL in the function
3173 silc_client_close_connection after executing the protocol's
3174 final callback since the sock might not be valid anymore.
3175 Affected file lib/silcclient/client.c.
3177 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Do not enable SILC_THREADS if the linking with libpthread
3180 did not happen. Affected file configure.in.pre.
3182 * Added notion to protocol specification that server must
3183 verify the sent authentication payload with CMODE when
3184 setting the channel founder key. Implemented it to the
3185 server. Affected file silcd/command.c.
3187 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Added _EXTRA_DIST SILC distribution variable to the
3190 distributions file. It is used to conditionally add extra
3191 files or directories to the specific distribution. Affected
3192 files ./prepare, Makefile.am.pre and distributions.
3194 Removed the `_' from the start of the distribution names.
3197 * Added README.WIN32 for instructions to compile the Toolkit
3200 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Fixed a double free in disconnection in the server. Affected
3203 file is silcd/server.c.
3205 * Fixed the lib/silcske/groups.c to work now also with GMP
3206 MP library. The string conversion did not work when using
3207 specific base and the base is indicated in the string as well.
3209 * Created win32/ directory which now includes MSVC++ specific
3210 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3211 It will appear only in the toolkit distribution
3213 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3215 * Changed the key material distribution function in case when
3216 the hash output is too short. The data is now concatenated
3217 a bit differently than it used to. Made the change to the
3218 SKE protocol specification.
3220 * Added better GMP detection to configure.in.pre. A patch
3223 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3225 * Fixed a minor bug in SKE that might cause some problem on
3226 some platforms. Affected file lib/silcske/silcske.c.
3228 * Added the cookie checking for initiator in the SKE. It checks
3229 that the responder returns the sent cookie unmodified. The
3230 affected file is lib/silcske/silcske.c. Added new SKE
3231 error type INVALID_COOKIE that can be sent during the
3232 negotiation. Fixed some memory leaks as well.
3234 * Added the "invalid cookie" error message to Irssi SILC client's
3237 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * Added `task_max' field to the SilcClientParams to indicate
3240 the maximum tasks the scheduler can handle. If set to zero,
3241 default values are used. Affected file lib/silcclient/silcapi.h.
3243 * Fixed memory leaks in silc_client_close_connection. Affected
3244 file lib/silcclient/client.c.
3246 * Added silc_client_del_client_entry to client library to free
3247 all memory of given client entry. Affected file is
3248 lib/silcclient/idlist.[ch].
3250 * Added new functions silc_client_del_channel and
3251 silc_client_del_server to delete channel and server entries.
3252 Affected file lib/silcclient/[silcapi.h/idlist.c].
3254 * Removed silc_client_del_client_by_id from silcapi.h.
3256 * Fixed the INFO command to return the server's own info
3257 correctly when querying by Server ID. Affected file is
3260 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * Removed the non-blocking settings in WIN32 code in the
3263 silc_sock_[read/write] and added SleepEx instead. Affected
3264 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3265 of input data is now checked with FIONREAD and ioctlsocket.
3267 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Call silc_schedule_task_del_by_context in the
3270 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3271 Affected file lib/silccore/silcprotocol.c.
3273 * Call silc_protocol_cancel for active protocols in the
3274 silc_server_close_connection if the funtion
3275 silc_server_free_sock_user_data has not been called.
3276 Affected file silcd/server.c.
3278 * Generic tasks cannot be deleted using the del_by_fd
3279 task deleting function since generic tasks does not match
3280 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3282 * Added a notion to SILCOPER help file that the SILCOPER works
3283 only on router server, not on normal server.
3285 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * Added for WIN32 support for the new scheduler as well.
3288 Affected file lib/silcutil/win32/silcwin32schedule.c.
3290 * Fixed the SHA1 implementation to work on various platforms.
3292 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3294 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3295 API. It is part of the scheduler now. Everything else is
3296 as previously but some functions has changed their names.
3297 Checkout the lib/silcutil/silcschedule.h for the interface.
3298 Updated all applications to use the new interface. Affected
3299 files are lib/silcutil/silcschedule.[ch].
3301 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Found a bug in the SKE implementation. The HASH value,
3304 specified by the protocol, was not computed correctly. The
3305 public key of the responder was not added to the computation
3306 even though it is mandatory. Affected file lib/silcske/silcske.c.
3307 This unfortunately causes incompatibilities with older
3308 clients and servers.
3310 * Added WIN32 specific network init and uninit functions:
3311 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3312 the Winsock2. Affected file lib/silcutil/silcnet.h and
3313 lib/silcutil/win32/silcwin32net.c.
3315 * Set the socket always to nonblocking mode on WIN32 after
3316 reading data or writing data. Affected file is
3317 lib/silcutil/win32/silcwin32sockconn.c.
3319 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Fixed various compilation problems under WIN32. Affected
3322 files lib/silcutil/win32/silcwin32thread.c and
3323 lib/silcutil/win32/silcwin32schedule.c.
3325 * Removed all _internal.h #includes from public header
3326 files. Internal headers must never be included from
3329 Removed also the lib/silcske/payload_internal.h file.
3331 * All include files that may be needed (public and some others
3332 included by the public headers) by application developers are
3333 now copied to the ./includes directory. It does not copy any
3334 internal headers. Affected file Makefile.defines.pre and all
3335 Makefile.am's under lib/ and subdirs.
3337 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3339 * Do not change the ~/.silc directory's permissions automatically.
3340 Affected file irssi/src/silc/core/clientutil.c.
3342 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3344 * Do not cancel the protocol in silc_server_close_connection
3345 it might cause recursion. Now cancelled in the function
3346 silc_server_free_sock_user_data. Affected file silcd/server.c.
3348 * Fixed the silc_server_remove_clients_by_server to regenerate
3349 the channel keys correctly finally. Added also new function
3350 silc_server_remove_clients_channels to actually do it.
3351 Affected file silcd/server.c.
3353 * Fixed the silc_server_new_channel to not crash by giving
3354 wrong router to the new channel. Affected file is
3355 silcd/packet_receive.c.
3357 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3360 which is given as argument to the silc_client_alloc now.
3361 It can be used to configure the client and set various parameters
3362 that affect the function of the client.
3364 * The USERS command in server did not check whether the channel
3365 is private or secret. Affected file silcd/command.c.
3367 * Added new argument to the USERS command in protocol specification.
3368 The USERS command now can take the channel name as argument
3369 as well. Added support for this in client and server and
3370 updated the protocol specs.
3372 * Completed the GETKEY command in client. It can be now used
3373 to fetch also servers public key not only some clients.
3374 Affected files lib/silcclient/command[_reply].c.
3376 * Added silc_client_get_server to return server entry by the
3377 server name. Affected files lib/silcclient/silcapi.h and
3380 * Redefined the IDENTIFY command in protocol specification to be
3381 more generic. It now can be used to query information about
3382 any entity in the SILC Network, including clients, servers and
3383 channels. The query may be based either the entity's name
3384 or the ID. Added support for this in both client and server.
3386 Affected files silcd/command.c and lib/silcclient/command.c
3387 and command_reply.c.
3389 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3390 the _from_client and _from_server functions. Affected file
3393 * Added silc_client_get_channel_by_id_resolve to the file
3394 lib/silcclient/silcapi.h to resolve channel information by
3395 its ID. Added also silc_client_get_channel_by_id that
3396 does not resolve it from the server.
3398 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * Added SilcServerEntry context into the client library
3401 to represent one server. The INFO command now allocates
3402 these to save the resolved server info. For now on the
3403 client library will also keep information about servers,
3404 connected and resolved with INFO.
3406 The INFO command now allocates the SilcServerEntry context
3407 and saves the server info there. The COMMAND_REPLY in
3408 the INFO now returns the parameters to application in
3409 same order as defined in the protocol specification.
3411 The entries are cached in the client->server_cache.
3413 * The INFO command is now issued after received the Client ID
3414 from the server. Affected file lib/silcclient/client.c.
3416 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3417 to the application as the mode changer might be server.
3418 It is guaranteed that NULL is not returned anymore to the
3419 application. Affected file lib/silcclient/client_notify.c.
3421 The ID Type is now also passed to the application so that
3422 it can check whether the returned entry is SilcClientEntry
3425 Added new function silc_client_get_server_by_id to return
3426 the server entry by ID. Affected files are the
3427 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3429 * Do not create the channel in the Irssi SILC Client when issuing
3430 the JOIN command but when received the sucessful JOIN command
3431 reply. Otherwise the channel might get created even though we
3432 could not join it. The Affected file is
3433 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3435 * Fixed a channel joining bug in router. The router must also
3436 check the channel modes, invite and ban lists etc. when serving
3437 the JOIN command sent by normal server. Affected file is
3438 silcd/command.c. The router now resolves the client's
3439 information from the server who sent the JOIN command if it
3440 does not know it, and processes the JOIN command only after
3443 * Changed the SilcCommandCb to take new argument; void *context2.
3444 Affected file lib/silccore/silccommand.h
3446 The second argument in the command callbacks in the server now
3447 includes the SilcServerCommandReplyContext if the command was
3448 called as pending command callback from the command reply.
3449 Otherwise it is NULL. When called as pending the status of the
3450 command reply will be checked and if it was erronous the
3451 error will be sent to the original sender of the command.
3452 This way the client always receives the error messages even
3453 though the server was actually the one who received the error
3454 when it resent the command to router, for example. Affected
3455 files silcd/command[_reply].[ch].
3457 * Fixed sending WHOWAS command's error message to client if
3458 the requested client could not be found. It was missing.
3461 * Changed the CMODE and CUMODE commands reply arguments in the
3462 protocol specification. The Channel ID is now sent in both
3463 of the commands to identify the channel. Implemented this
3464 new feature to the client and server. Affected files
3465 lib/silcclient/command_reply.c and silcd/command.c.
3467 * Made better checks for invite and ban lists in the JOIN
3468 command in server. Affected file silcd/command.c.
3470 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * The server now performs the incoming host IP/DNS lookup
3473 using the silc_socket_host_lookup and thus does not block
3474 the server anymore. Affected file silcd/server.c.
3476 * Completed the multi-thread support for SILC Scheduler in
3477 the lib/silcutil/silcschedule.c.
3479 * Fixed the configure.in.pre to detect the pthread correctly
3482 * Fixed a deadlock in silc_task_queue_wakeup in the file
3483 lib/silcutil/silctask.c.
3485 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Added new function silc_schedule_wakeup that is used in
3488 multi-threaded environment to wakeup the main thread's
3489 schduler. It needs to be used when a thread adds a new task
3490 or removes a task from task queues. After waking up, the
3491 scheduler will detect the task queue changes. If threads
3492 support is not compiled in this function has no effect.
3493 Implemented the wakeup mechanism to both Unix and WIN32
3494 systems. Affected files are lib/silcutil/silcschedule.[ch],
3495 lib/silcutil/unix/silcunixschedule.c and the
3496 lib/silcutil/win32/silcwin32schedule.c.
3498 * Added new function silc_task_queue_wakeup to wakeup the
3499 scheduler by the specified task queue. Affected file
3500 lib/silcutil/silctask.[ch].
3502 * The silc_socket_host_lookup_start now wakes up the scheduler
3503 after adding the timeout task. Affected file is
3504 lib/silcutil/silcsockconn.c.
3506 * The silc_socket_host_lookup is synchronous now if the threads
3507 support is not compiled in. However, the callback is still
3508 called asyncronously through the scheduler, anyway. Affected
3509 file lib/silcutil/silcsockconn.c.
3511 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3513 * Added new function silc_socket_host_lookup to perform
3514 asynchronous IP and FQDN lookups for the socket connection.
3515 Affected files lib/silcutil/silcsockconn.[ch].
3517 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3519 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3520 that may or may not compile the mutex support in.
3522 Changed the silc_mutex_alloc interface. It allocates the
3523 mutex now to the sent pointer and returns TRUE or FALSE.
3525 Affected file lib/silcutil/silcmutex.h.
3527 * Wrote the SILC Task Queue interface to support multi-threads.
3528 Affected file lib/silcutil/silctask.[ch].
3530 * Wrote the SILC Scheduler to support multi-threads. Affected
3531 file lib/silcutil/silcschedule.c.
3533 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3535 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3536 in lib/silcutil/win32/.
3538 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Defined SILC Mutex API and SILC Thread API and implemented
3541 them for Unix. Affected files are
3542 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3543 lib/silcutil/unix/silcunixmutex.c and
3544 lib/silcutil/unix/silcunixthread.c.
3546 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Fixed the silc_server_remove_clients_by_server's channel
3549 key re-generation. The hash table handling was incorrect
3550 and would not work with many channels. Affected file is
3553 * Fixed some memory leaks around the server code.
3555 * Rewrote the silc_server_get_users_on_channel to support IPv6
3556 based Client ID's. Affected file silcd/server.c.
3558 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3559 specification. However, a separate document must be written
3560 to define the detailed signing procedure and the payload
3561 associated with the flag. Defined the flag to the
3562 lib/silccore/silcchannel.h as well.
3564 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * Changed the dynamic tables to static size tables in the
3567 lib/silccrypt/silchmac.c.
3569 * Removed GCC dependencies from the code. A patch by cras.
3571 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3573 * Do not show the error "Error receiving packet bla bla"
3574 in server if it really was not an error (-2 means that reading
3575 is pending). Affected file silcd/server.c.
3577 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Fixed a possible crash in silc_server_remove_clients_by_server
3580 in silcd/server.c. Fixed there also some memory leaks.
3582 * Fixed the silc_idlist_replace_client_id. It could replace
3583 wrong key in the hash table. Affected file silcd/idlist.c.
3585 * Do not check whether there are global users on the channel
3586 if the channel->global_users is FALSE. Affected functions
3587 silc_server_remove_from_one_channel and
3588 silc_server_remove_from_channels in silcd/server.c. Also,
3589 do not check if the removed client is local as we can be
3590 sure that global client was not removed from the channel
3591 and checking for global users is not needed.
3593 * The silc_server_remove_clients_by_server now re-generates
3594 the channel keys correctly for those channels that had
3595 clients removed from them. Affected file silcd/server.c.
3597 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3599 * Found the reason of random crashes in the server. We weren't
3600 ignoring the SIGPIPE signal (which can be sent in write())
3601 and it crashed the server. Affected file silcd/silcd.c.
3603 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Assure that sock->user_data is not NULL in the function
3606 silc_server_packet_send in silcd/packet_send.c.
3608 * Disconnect the remote connection if it could not be added
3609 to any ID lists in the server. The affected file is
3612 * Check in silc_server_packet_send[_real/dest] that the
3613 socket is not disconnecting and ignore the data if it is.
3614 Affected file silcd/packet_send.c.
3616 * Define inline to __inline on native WIN32 compilation.
3617 Affected file includes/silcwin32.h.
3619 * Added some explicit type casts for inline code since MSVC
3620 require them. Affected files lib/silcutil/silcbuffer.h,
3621 lib/trq/silcdlist.h and lib/trq/silclist.h.
3623 * Print warning in log files from now on if the packet
3624 decryption fails. Affected file silcd/server.c.
3626 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Changed the `say' client operation's interface to accept
3629 new `type' argument to indicate the type of the message sent
3630 by the library. The application may filter the library's
3631 messages according the type. The affected file is the
3632 lib/silcclient/silcapi.h.
3634 * Added two new functions to lib/silcclient/silcapi.h:
3635 silc_client_del_client and silc_client_del_client_by_id.
3636 Affected file lib/silcclient/idlist.c.
3638 * Moved the clientincludes.h from includes/ to silc/ and
3639 serverincludes.h from includes/ to silcd/.
3641 * The modes for the CMODE and CUMODE are now passed as
3642 uint32 for application with COMMAND_REPLY. The affected
3643 file is lib/silcclient/command_reply.c.
3645 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3647 * /WHOIS without arguments shows client's own information.
3648 Affected file lib/silcclient/command.c.
3650 * Changed PING to not accept any arguments. The specs
3651 says that client can ping only the connected server so
3652 requiring an argument is not needed. Affected file is
3653 lib/silcclient/command.c.
3655 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3657 * Fixed a fatal bug in private message sending and reception
3658 encryption and decryption when using private message keys.
3659 The implementation was incorrect and did not follow the
3660 specification. It causd that some of the message were
3661 lost since it did not use the sending and receiving keys
3662 as the protocol suggests. This has been fixed and will cause
3663 incompatibilities with older clients when sending private
3664 message encrypted with private message keys. Affected files
3665 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3666 and various other in Irssi SILC Client.
3668 Added `responder' boolean argument to the functions
3669 silc_client_add_private_message_key[_ske] to indicate when
3670 the key is added as responder or initiator of the key
3673 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Removed the silc_ske_check_version function and created
3676 a SilcSKECheckVersion callback. Added also a function
3677 silc_ske_set_callbacks that is now used to set all SKE
3678 callbacks. The callback functions are not given to
3679 the SKE functions anymore, but this function is used to
3682 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3684 * Added `silc_version' argument to the silc_client_alloc
3685 to define the version of the application for the library.
3686 The library will use the version string to compare it
3687 against the remote host's (usually a server) version
3688 string. Affected file lib/silcclient/silcapi.h
3690 * Added the KE protocol context to Key Agreement context
3691 in client library so that we can abort the SKE if it
3692 is in process when we get timeout. Affected file is
3693 lib/silcclient/client_keyagr.c.
3695 * Do not resolve the client ID forever if it returns in the
3696 first time that such client does not exist. This was done
3697 for example with private message. Affected file is
3698 lib/silcclient/client_prvmsg.c.
3700 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * Do not add regex.h for WIN32. The affected file
3703 includes/silcincludes.h.
3705 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3706 not work yet 100%. It generates the DLL's automatically
3707 when compiling with --with-win32 under cygwin.
3709 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3711 * lib/contrib/regex.c is not compiled on WIN32.
3713 * Added silc_net_get_socket_opt function to the
3714 lib/silcutil/silcnet.h.
3716 * Added includes/silcwin32.h for WIN32 specific includes
3719 * Do not use ptime structure or any of the posix process
3720 functions on WIN32 in lib/silccrypt/silrng.c.
3722 * Added silc_gettimeofday to provide generic function
3723 for struct timeval on all platforms. Added the function
3724 to lib/silcutil/silcutil.h.
3726 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3728 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3729 library as they clearly belong there. As a plus side we
3730 can make the actual socket connection routines platform
3733 Added also new generic function silc_socket_read and
3734 silc_socket_write (that used to be silc_packet_[read/write].
3735 The implementation of these are platform specific.
3737 * Added WIN32 specific routines of silc_socket_[read/write]
3738 to lib/silcutil/win32/silcwin32sockconn.c.
3740 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3742 * Added preliminary support for native WIN32 compilation under
3743 cygwin (using the -mno-cygwin option for GCC) to the
3744 ./configure.in.pre. The --with-win32 now prepares the
3745 compilation for native WIN32.
3747 * Rewrote the SILC Scheduler interface in the file
3748 lib/silcutil/silcschedule.h. The scheduler is now context
3749 based and does not have anymore any global static scheduler.
3750 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3751 and created lib/silcutil/win32 directory for WIN32 based
3754 * Added Unix specific network routines to the
3755 lib/silcutil/unix/silcunixnet.c and the old
3756 lib/silcutil/silcnet.c includes now only generic routines.
3758 Added WIN32 specific network routines to the
3759 lib/silcutil/win32/silcwin32net.c.
3761 * Added Unix specific utility functions from the
3762 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3764 * Added WIN32 SILC Scheduler to the file
3765 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3768 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3770 * Do not handle JOIN notify in the server if the target client
3771 is not registered (idata->registered == FALSE). The affected
3772 file is silcd/packet_receive.c.
3774 * Update the nickrec->founder in event_cumode in the Irssi SILC
3775 client. Affected file irssi/src/silc/core/silc-channels.c.
3777 * Fixed the CUMODE_CHANGE notify handling in the server when
3778 server and router are announcing their clients on channels.
3779 Now the mode changes are saved and notified correctly. The
3780 affected file is /silcd/packet_receive.c.
3782 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3783 They really did not replace the cache entry in the ID Cache.
3784 Now they do that. Affected file silcd/idlist.c.
3786 * Fixed the KICK notify handling in the Irssi SILC client to
3787 update the channel records so that the kicked client does not
3788 appear to be on the channel. The affected file is
3789 irssi/src/silc/core/silc-channels.c.
3791 * Always update the conn->current_channel when executing command
3792 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3794 * Fixed the KILL notify handling in Irssi SILC client to remove
3795 the killed client on all channels.
3797 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Fixed the silc_parse_command_line to remove extra spaces
3800 from the start and end of the arguments. Affected file is
3801 lib/silcutil/silcutil.c.
3803 * Cancel and free any active protocol in the function
3804 silc_server_close_connection. Affected file silcd/server.c.
3806 * Cancel and free any active protocol in the function
3807 silc_client_close_connction. Affected file is
3808 lib/silcclient/client.c.
3810 * Do not execute the KILL command for clients that are in
3811 history (ie. they are not in the network). Affected file is
3814 * Fixed KILL notify handling, client does not crash anymore.
3815 Affected file irssi/src/silc/core/silc-channels.c.
3817 * Reduced the default packet buffer size from 2048 to 1024 in
3818 lib/silccore/silcpacket.c.
3820 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3821 counter to the SKE context that is incresed when the SKE library
3822 performs async operation outside the library. If the outside
3823 process frees the SKE context and FREED status will be set
3824 and the library will detect after the sync operation that the
3825 libary is freed. The affected files are
3826 lib/silcske/silcske[_status].[ch].
3828 * Resolve the client entry information in the function
3829 silc_client_channel_message to assure that NULL pointer is not
3830 passed as client entry to the application. */
3832 * Fixed the task timeout calculation to assure that there is
3833 never negative timeouts. The affected file is
3834 lib/silcutil/silcschedule.c.
3836 * Fixed the channel user mode notification sending in server.
3837 It was sent point-to-point to the router (or to server by router)
3838 but it needs to be destined to a channel. The routines now
3839 supports sending the channel user mode notifys to the channels
3840 when announcing clients and channels. Affected files are
3841 silcd/server.c and silcd/packet_receive.c.
3843 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3844 It did not actually replace the old channel entry in the cache.
3845 Affected file lib/silcclient/client_notify.c.
3847 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Fixed a possible crash in silc_packet_send_prepare. It now
3850 assures always that there is enough space in the buffer and
3851 at the tail area of the buffer (for MAC).
3853 Fixed the inbound buffer reallocation in silc_packet_read.
3854 It was old code and did not handle the reallocation correctly.
3857 The affected file is lib/silccore/silcpacket.c.
3859 * Fixed buffer overflow in silc_parse_nickname in the file
3860 lib/silcutil/silcutil.c.
3862 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * make install generates new server keys only if there is not
3867 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3870 Added check that if the NOREPLY is set then we will not send
3871 the away message. This avoids infinite loop of away messages
3872 if both clients are away. The affected file is
3873 lib/silcclient/client_prvmsg.c.
3875 * Fixed client crash if /NICK was given without arguments.
3876 Affected file lib/silcclient/command.c.
3878 * Server does not send the invite list in INVITE command back
3879 to the client if the list was not altered. Added this notion
3880 to the protocol spec as well. Affected file silcd/command.c.
3882 Fixed possible crash in INVITE command by checking the
3883 value of silc_server_get_client_route command.
3885 * Fixed the INVITE notify type handling. The arguments are now
3886 taken in correct order and client does not crash. The affected
3887 file is irssi/src/silc/core/silc-channels.c.
3889 Removed the "Inviting xxx to channel" message from the
3890 client library away and let the application handle it.
3891 Affected file lib/silcclient/command.c. Added that message
3892 to Irssi SILC client's message formats.
3894 * Fixed CMODE command crash in client. It now checks the
3895 amount of arguments correctly and does not crash. The affected
3896 file is lib/silcclient/command.c.
3898 * Do not create new channel automatically in silc_channels_join
3899 but check whether the channel by that name already exists.
3900 Affected file irssi/silc/core/silc-channels.c.
3902 * Do not send the SERVER_SIGNOFF to router if the disconnected
3903 entity was the router. Affected file silcd/server.c.
3905 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3906 SILC client as it was missing from there.
3908 Added the handling of the KICK notify to the Irssi SILC client
3909 as it was missing. Added "you have been kicked" message to
3910 Irssi SILC client's message modules formats.
3912 Added the handing of the KILL notify to the Irssi SILC client
3913 as it was missing. Added the kill message module formats
3916 The affected file is irssi/src/silc/core/silc-channels.c.
3918 * The router did not save the channel mode the server announced.
3919 Affected file silcd/packet_receive.c.
3921 * Fixed a possible crash in INFO command in server. If the
3922 server did not provide the server info it crashed. Affected
3923 file silcd/command.c.
3925 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Fixed the GETKEY command in the server to check also the
3928 global list. Otherwise the GETKEY would not work correctly
3929 in normal SILC server. Affected file silcd/command.c.
3931 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Fixed GETKEY crash, it crashed if the command did not succseed.
3935 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3938 is now real and not just an macro interface to GMP.
3940 Removed the entire GMP from the source tree and imported new
3941 NSS MPI library instead. Reason for removing GMP is that it is
3942 extremely large and compiles extremely slow. The NSS MPI
3943 is only a few files and compiles in less than 10 seconds.
3944 The speed is also about the same as GMP. The MPI is imported
3945 to lib/silcmath/mpi.
3947 If the system has GMP installed we will still use the GMP.
3948 If it is not then the NSS MPI will be compiled.
3950 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Merged a long nickname (127 characters long) crash bugfix from
3953 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3955 * Merged a freed memory reference bugfix from Irssi CVS tree.
3956 Affected file irssi/src/core/commands.c.
3958 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Added the server's public key sving and verification to the
3961 server when performing the SKE. This was missing and the
3962 remote server's (or router's) public key was accepted without
3963 checking whether we have it previously or trust it at all.
3964 Affected file silcd/protocol.c.
3966 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Check in the silc_server_timeout_remote if protocol is active
3969 and make sure that the protocol's final callback is called so
3970 that all memory if freed. Affected file silcd/server.c.
3972 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * silc_server_whois_send_reply crashed the server if the nickname
3975 was 127 characters long. Affected file silcd/command.c.
3977 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Added sanity check to the silc_server_new_client. If the hostname
3980 is provided inside username then check that the provided hostname
3981 really is the same as the resolved one. If the hostname was not
3982 resolved then check it from the public key. Affected file is
3983 silcd/packet_receive.c.
3985 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3986 if the server disconnected us and the connection is not valid
3987 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3989 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3990 the library to the lib/silcutil/silcutil.[ch].
3992 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Close log file after open. Affected file
3995 lib/silcutil/silclog.c.
3997 * Check whether sock == NULL in silc_client_send_packet and return
3998 if it is. Affected file lib/silcclient/silcclient.c.
4000 * Check rec->entry == NULL in the Irssi SILC Client before
4001 sending the channel message. Affecte file is
4002 irssi/src/silc/core/silc-servers.c.
4004 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Merged a splitted window bugfix from Irssi CVS tree. The
4007 affected file is irssi/src/fe-text/textbuffer-view.c.
4009 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4010 It did not print nickname.
4012 * Improved the distributions system a bit.
4014 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4017 irssi/src/fe-text/gui-window.c.
4019 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4020 to in-active server. The affected file is
4021 irssi/src/silc/core/client_ops.c.
4023 * Resolve the client in USERS command reply if the entry does
4024 not have username resolved. The affected file is
4025 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4026 command to WHOIS command to really resolve stuff. The USERS
4027 is not used any more in any critical section so WHOIS can
4028 be used even though it might be slower than IDENTIFY.
4030 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4033 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Changed the protocol API a bit more consistent in the
4036 lib/silccore/silcprotocol.[ch].
4038 * Changed the following headers to ROBODoc format:
4040 lib/silccore/silcpayload.h
4041 lib/silccore/silcprotocol.h
4042 lib/silccore/silcsockconn.h
4044 All core library headers are now formatted.
4046 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Fixed a bug in Irssi SILC client; do not show that you are
4049 server/router operator if you really are not. Affected file is
4050 irssi/src/silc/core/client_ops.c.
4052 * Renamed silc_command_free_payload to silc_command_payload_free.
4053 Affected file lib/silccore/silccommand.h
4055 * Added silcmath.h to include the prototoypes of various routines
4056 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4059 * Changed the following headers to ROBODoc format:
4061 lib/silccore/silcchannel.h
4062 lib/silccore/silccommand.h
4063 lib/silccore/silcid.h
4064 lib/silccore/silcidcache.h
4065 lib/silccore/silcmode.h
4066 lib/silccore/silcnotify.h
4067 lib/silccore/silcpacket.h
4068 lib/silcmath/silcmath.h
4070 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Added checking to the server code not to start the server if
4073 ciphers and stuff are not configured properly. Affected files
4074 silcd/serverconfig.[h] and silcd/server.c.
4076 * Changed the layout of the header files of the public interfaces
4077 in the SILC libraries. The new layout supports ROBODoc
4078 documentation tool (and some others) so that it is easy to create
4079 a library reference manual. All the other headers and source
4080 code must still follow the CodingStyle document. Also source
4081 code must not include these ROBODoc stuffs, only the headers.
4082 Furthermore, all public interface headers must now be named
4083 by using `silc' prefix, example: silcapi.h, silccipher.h.
4084 Some files were renamed due to this. All the other headers
4085 must not be used as public interfaces. I will update the
4086 CodingStyle document later. Changed following headers, so far:
4088 lib/silcclient/silcapi.h
4089 lib/silccore/silcauth.h
4090 lib/silccore/silcprivate.h
4091 lib/silccrypt/silcdh.h
4093 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Removed silc_client_packet_send_flush from the client library
4098 as it is not needed. Affected file lib/silcclient/client.[ch].
4100 * Added printing of message of unresolved authentication method
4101 to the Irssi SILC client. Added it to the module formats.
4102 Removed the same message from the client library.
4104 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Added new distribution feature, DISTLABEL. Every distribution
4107 can define own preprocessor label that can be used in the
4108 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4109 file distributions, acconfig.h.pre and prepare.
4111 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Added Makefile.defines_int to include the actual definitions
4114 for Makefile.defines.in. Tested the new distribution system,
4115 created distributions and tested installation.
4117 * Added AWAY message printing to the Irssi SILC client. Added
4118 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4120 * Added SCONNECT command to call the SILC's CONNECT command.
4121 Cannot use CONNECT directly since Irssi uses that internally.
4122 Affected file irssi/src/silc/core/silc-servers.c.
4124 Added ACTION local command. It is same as ME command but takes
4125 the channel as mandatory argument.
4127 Rewrote some of the Irssi's help files to suite for SILC
4130 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Added Makefile.defines[.in] that should for now on be included
4133 in all Makefile.am file in the source tree. That file includes
4134 all common compilation definitions for SILC source tree.
4136 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Minor changes to the ./prepare script to change the package
4139 name according the distribution name to the configure.in.
4141 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Created new distribution system. Added file `distributions'
4144 that defines all the distributions that can be created out of
4145 the SILC source tree. The ./prepare script now reads that
4146 file to determine how to prepare the distributions. The
4147 first argument to the ./prepare is the name of the distribution
4148 and second is the version of the distribution. If given
4149 without arguments it creates the default (toolkit) distribution
4150 with the default version (defined in ./prepare).
4152 All Makefile.am files that are subject to the distributions
4153 are now named as Makefile.am.pre. These are ./Makefile.am
4154 and lib/Makefile.am. Others may be changed later.
4156 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Added invite list, ban list, some key management and connection
4159 error message printing to module formats in the Irssi SILC client.
4161 * Added new silc_client_set_away_message to set the away message
4162 that is back to the person who sent private message. The
4163 affected file lib/silcclient/silcapi.h and the
4164 lib/silcclient/client_prvmsg.c.
4166 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed the private message sending in the Irssi SILC client,
4169 added local command KEY to the Irssi SILC client.
4171 Added key management and key agreement message formats to the
4172 irssi/src/fe-common/silc/module-formats.[ch].
4174 Added USERS (alias WHO) printing, server/router operator
4175 indication and LIST command printing to the module formats.
4177 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Fixed channel joining notify handling, cumode notify handling
4180 from Irssi SILC client.
4182 * Added SILC specific module-formats to the Irssi SILC client so
4183 that SILC specific message hilighting, colors etc is possible.
4184 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4186 Added channel mode, channel user mode, actions, notices,
4187 whois and whowas printing to the the module-formats.c.
4189 * Fixed a bug in channel deletion in the server. The channel
4190 is not left to the cache even if the channel founder auth mode
4191 is set when there are no users anymore on the channel. Affected
4192 file silcd/server.c.
4194 * The silc_net_localhost now resolves the entire hostname including
4195 the domain name. Affected file lib/silcutil/silcnet.c.
4197 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Changed the ask_passphrase client operation to be ascynchronous.
4200 It has now a completion callback and a context that the
4201 application must call after it has got the passphrase from
4202 the user. Affected files lib/silcclient/silcapi.h,
4203 lib/silcclient/protocol.c, lib/silcclient/command.c and
4206 Added SilcAskPassphrase callback that the application calls
4207 to deliver the passphrase to the library.
4209 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4210 The public key verification and especially a certificate
4211 verification is asynchronous procedure.
4213 Added new SILC_SKE_STATUS_PENDING status to indicate the
4214 request is pending and a callback will be called to finalize
4217 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4218 indicate that remote end did not send its public key (or
4219 certificate), even though we require it. Added check for this
4220 condition in the SKE. This was a security bug, now fixed.
4222 Defined new SilcSKEVerifyCbCompletion callback that is called
4223 when the verification process is completed.
4225 The affected files lib/silcske/silcske_status.h and
4226 lib/silcske/silcske.[ch].
4228 * Changed the verify_public_key client operation to be async
4229 as well. Defined SilcVerifyPublicKey callback that is used to
4230 indicate the success of the public key verification process.
4232 Changed the server and client to use the new async client
4235 * Changed the Irssi SILC client's internal scheduler to be called
4236 twice as many times as it used to be. As a result the client
4237 should be a bit faster now. Affected file is
4238 irssi/src/silc/core/silc-core.c.
4240 * Added support to Irssi SILC client of asynchronous public key
4241 verification and passphrase inquiry. Affected file is
4242 irssi/src/silc/core/silc-core.c.
4244 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Do not say "You have left channel %s" in client library.
4247 Moved it to the application. Affected files are
4248 lib/silcclient/command.c and silc/client_ops.c.
4250 * Fixed silc_client_get_clients. Command context was not
4251 duplicated and was freed memory in the callback. Affected
4252 file lib/silcclient/idlist.c.
4254 * Do not say "you are now talking..." on JOIN command in the
4255 client library. The appliation must handle it.
4257 * Do not say ".. changed topic to" in command reply in the
4258 client libary. The application must handle it.
4260 * Fixed TOPIC command sending in the client library.
4262 * Fixed a memory leak in silc_client_command_free in the file
4263 lib/silcclient/command.c.
4265 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Imported a modified version of Irssi client to the source tree.
4268 The Irssi will be used to create a new client called
4269 Irssi SILC. Imported to irssi/.
4271 Added silc_core_init_finish function to the Irssi. Affected
4272 file irssi/configure.in.
4274 A lot changes in the Makefile.ams around the irssi tree.
4276 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Do not rehash if the new size is same as the old size of the
4279 hash table, in the silc_hash_table_rehash*. The affected file
4280 lib/silcutil/silchashtable.c.
4282 * Replaced hash_table_del_by_context calls from the server
4283 (when channel->user_list and client->channels) to the
4284 hash_table_del as it is sufficient and faster.
4286 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Added silc_hash_table_list, silc_hash_table_get and the
4289 SilcHashTableList structure to provide an alternative way to
4290 traverse the hash table. The affected files are
4291 lib/silcutil/silchashtable.[ch].
4293 * Changed the server's idlist routines to use the hash table
4294 routines to optimize the code.
4296 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Replaced the client entry's `channel' list and channel entry's
4299 `user_list' list to hash tables for optimized lookup. Changed
4300 the code to use the hash table interface around the code.
4301 Affected file lib/silcd/idlist.[ch].
4303 * Added `auto_rehash' boolean argument to the function
4304 silc_hash_table_alloc to indicate whether the hash table should
4305 auto-rehash when it thinks is appropriate time. It will
4306 increase the hash table size if the there is twice as much
4307 entries in the table than the size of the table, and will
4308 decrease the size if there are twice as less entries than
4309 the size of the table.
4311 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4315 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * silc_idcache_purge_by_context deletes the entry now by context
4318 as it is supposed to do. Affected file lib/silccore/idcache.c.
4320 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4321 client is not anymore valid (WHOWAS givens the info) and not
4322 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4324 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Removed the `data' and `data_len' arguments from the ID Cache
4327 interfaces and added `name' argument. ID Cache does not handle
4328 anymore the binary data only a names associated with given ID.
4330 * When hashing a Client ID with silc_hash_id the entire ID is
4331 not hashed anymore, instead only the hash of the Client ID is
4332 hashed. This way we can access the Client ID from the cache
4333 with Client ID but with the hash of the ID (which is a hash of
4334 the nickname) as well without any difference in performance.
4336 Added also silc_idcache_find_by_id_one_ext to do one on one
4337 searching when we have the actual ID. Added also function
4338 silc_hash_client_id_compare. The affected files are
4339 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4341 * When hashing the name associated with a ID it is always done
4342 in lowercase. This way we can access the cache without worrying
4343 about case-sensitivity, even though, for example nicknames are
4346 * Fixed a bug in server with channel message sending. It put
4347 wrong ID type as destination ID. The affected file
4348 silcd/packet_send.c.
4350 * silc_idcache_del_by_context now deletes from all hash tables
4351 by context. Affected file lib/silccore/idcache.c.
4353 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Changed the client library to use the new ID Cache interface.
4356 Changes around the source tree.
4358 * Added silc_hash_table_rehash_ext to rehash with specific
4359 hash function. Affected file lib/silcutil/silchashtable.[ch].
4361 * Added silc_hash_string_compare to compare two strings in the
4362 hash table. Affected file lib/silcutil/silcutil.[ch].
4364 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Added new function silc_idcache_del_by_context into the
4367 lib/silccore/idcache.[ch].
4369 * Changed the server's ID list routines to use the new ID Cache
4370 interface. Changes around the source tree.
4372 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Added silc_hash_table_del[_by_context]_ext functions in to the
4375 lib/silcutil/silchashtable.[ch].
4377 Removed silc_hash_table_find_all* routines and added new
4378 silc_hash_table_find_foreach to replace them.
4380 Added silc_hash_table_replace_ext function as extended
4381 replacing function. Separated the simple hash table interface
4382 from the extended hash table interface in the file
4383 lib/silcutil/silchashtable.h.
4385 * Fixed minor bugs and changed it to use some of the new
4386 hash table functions in lib/silccore/idcache.c
4388 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added new function silc_hash_table_find_all to return all keys
4391 in the hash table by the specified key. As the hash table is
4392 collision resistant it also makes it possible to have several
4393 duplicate keys in the hash table. This function may be used to
4394 find all of the keys from the hash.
4396 Added user_context arguments to the SilcHashFunction,
4397 SilcHashCompare and SilcHashDestructor to deliver user specified
4400 Added new fuctions silc_hash_table_find[_all]_ext to do
4401 extended lookup with specified hash and compare functions and
4402 specified user contexts.
4404 Added new function silc_hash_table_add_ext to add the key
4405 with specified hash function and user context.
4407 Added new function silc_hash_table_foreach to traverse all
4408 entrys in the hash table. Added SilcHashForeach callback
4411 Added new function silc_hash_table_del_by_context to delete
4412 the entry only if the context associated with the key matches.
4414 Affected files are lib/silcutil/silchashtable.[ch].
4416 * Removed silc_hash_[server/client/channel]_id and added just
4417 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4418 silc_hash_id_compare to compare two ID's using as the hash table
4419 comparison function. Added also silc_hash_data to hash
4420 binary data and silc_hash_data_compare to compare it.
4422 * Removed silc_idlist_find_client_by_hash as it is not needed
4423 anymore. Affected file silcd/idlist.[ch].
4425 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4426 to use internally the SilcHashTable. The new ID Cache is a lot
4427 faster than the old one. Some of the ID Cache interface was also
4428 rewritten and obsolete and stupid functions were removed.
4430 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Added entry_count field to the SilcHashTable to keep the number
4433 of the entries in the table. Implemented the function
4434 silc_hash_table_rehash. Added new function
4435 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4437 Fixed a minor bug in silc_hash_table_free.
4439 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4440 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4441 into the lib/silcutil/silcutil.[ch].
4443 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Implemented a collision resistant hash table into the
4446 lib/silcutil/silchashtable[ch]. See the header and the source
4447 for the SilcHashTable API.
4449 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Merged dotconf version 1.0.2 into lib/dotconf.
4453 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Do not compile anything in lib/silcsim/* if the SIM support
4456 is not enabled. The tree should now compile without problems
4459 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Compiled the SILC under cygwin. Compiled and tested briefly
4462 without problems. More tests needed. The SIMs didn't compile
4465 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4467 * Fixed possible crash in silc_get_username in the
4468 lib/silcutil/silcutil.c.
4470 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Fixed a va_arg in silc/client_ops.c.
4474 * Oops, RC5 routines were named AES and caused some problems
4475 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4477 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Added new SilcIDIP structure into the lib/silccore/id.h and
4480 replaced the old `ip' fields from all SILC ID's to that type.
4481 This is a step towards IPv6 support.
4483 The silc_id_get_len takes now the ID as an extra argument.
4484 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4485 both IPv4 and IPv6 based ID's.
4487 The affected files are lib/silccore/id.[ch] and other files
4488 around the tree using these routines.
4490 * Removed the ID length arguments in server from various
4491 silc_server_send_notify_* routines -> they are not needed
4494 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Fixed memory leak in silc_encode_pem_file in the file
4497 lib/silcutil/silcutil.c.
4499 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Check minor version as well in the SKE. Affected files are
4502 silcd/protocol.c and lib/silcclient/protocol.c.
4504 * Added --identifier option to the server so that an identifier
4505 can be when creating the public key for the server. Affected
4506 file is silcd/silcd.c.
4508 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4509 lib/silccrypt/silcpkcs.c.
4511 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Register default ciphers and stuff when using -C option with
4514 the server. Affected file sildc/silcd.c.
4516 * Put back the servers public key filename format, it is better
4517 than the new one. For now, the client keys are saved with the
4518 new filename format. The affected file silc/client_ops.c.
4520 * Implemented the Cipher API for the rest of the ciphers that
4521 did not implement it or implemented it the wrong way.
4523 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Register default ciphers and stuff when using the -S option
4526 in the client. Affected file silc/silc.c. Same also when
4527 creating new key pair with -C option.
4529 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Fixed the silc_verify_public_key client operation function to
4532 save the public keys differently. The fingerprint is now
4533 used as filename and not the hostname. This way also the
4534 client keys are saved uniquely and not with hostnames. The
4535 affected file is silc/client_ops.c.
4537 * Trimmed the silc_hash_fingerprint function to remove extra
4538 whitespaces from the end of the fingerprint. The affected
4539 file is lib/silccrypt/silchash.c.
4543 * Added silc_cipher_register_default function to register all
4544 default ciphers. It can be used when configuration files
4545 does not exist and the application does not want any specific
4546 ciphers in any specific order.
4548 The SilcDList is now used as silc_cipher_list dynamically
4549 allocated cipher list. Removed the static list all together
4550 and now all ciphers must be allocated to the dynamic list.
4551 The silc_cipher_alloc routine was changed to check only the
4554 All silc_cipher_* routines that used to return int returns
4557 The affected files lib/silccrypt/silccrypt.[ch].
4559 * The same thing was done to silc_hash_* as for silc_cipher_*
4560 routines. Affected files lib/silccrypt/silchash.[ch].
4562 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4563 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4564 Added also silc_pkcs_[un]register[_default] functions.
4565 Removed the data_context from the PKCS API.
4567 * Added silc_hmac_register_default function to register default
4568 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4569 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4570 to unregister all hmacs at once.
4572 * Register the default ciphers, hash functions, PKCSs and HMACs
4573 if client's configuration file does not exist. The affected
4576 * The client did not load the hash functions from the SIM
4577 modules at all. Added support for this. Affected file is
4578 silc/clientconfig.c.
4580 * When decoding public key with silc_pkcs_public_key_decode, check
4581 the supported algorithm only if PKCS are registered. Affected
4582 file lib/silccrypt/silcpkcs.c. The same was done with the
4583 silc_pkcs_private_key_decode.
4585 * Fixed the SILC List routines to keep the list always in order.
4586 It used to change the list's order when traversing the list but
4587 not it preserves the order. Affected file lib/trq/silclist.h.
4589 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Added the client library to use the SilcSocketConnection's
4592 reference counter (by silc_socket_dup) to prevent the bug that
4593 the socket object may be freed underneath async operation.
4595 * The name resolv library checking fixes in the configure.in.pre.
4598 * Created new version of the protocol drafts for future
4599 development. The -03 drafts are the ones that will be changed
4600 in the trunk now and the -02 will remain as they are.
4602 * Send list of CUMODE notifys to the router when announcing
4603 the channel users to the router. Affected file silcd/server.c.
4604 If the router receiving channel founder CUMODE for a channel
4605 that already has channel founder it will send CUMODE notify
4606 to the sender to remove the channel founder rights from the
4607 announced client. Affected file silcd/packet_receive.c.
4609 * The CUMODE notify may now use Server ID as well as the entity
4610 who changes the mode. Updated protocool specs.
4612 * Updated INSTALL and README files.
4614 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * New web pages in the http://silc.pspt.fi. The pages was
4621 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Implemented the [DenyConnectin] config section in the server.
4624 Added silc_server_config_denied_conn to check whether incoming
4625 connection is denied. Affected file silcd/serverconfig.[ch].
4627 * Do not check the ports when checking the incoming configuration
4628 data if the port is 0, meaning any. Affected file is
4629 silcd/serverconfig.c.
4631 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Fixed buffer overflow in silc_string_compare in the file
4634 lib/silcutil/silcutil.c.
4636 * Fixed double free in silc_server_command_leave in the file
4639 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Fixed the version checking in the server. Affected file is
4644 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Fixed the configuration data fetching when accepting new
4647 connections in the server. Affected file silcd/server.c.
4649 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Added `sender_entry' argument to the function
4652 silc_server_packet_relay_to_channel so that we can check
4653 whether some destination actually belongs to the same route
4654 the sender belongs (ie, we must not resend the packet to the
4655 sender). Affected file silcd/packet_send.[ch].
4657 * Added `servername' field to the SilcClientEntry in the server
4658 to hold the name of the server where client is from. Affected
4659 file is silcd/idlist.h.
4661 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Moved the channel message encrypting in the router betwen
4664 router connections from silc_server_channel_message to the
4665 silc_server_packet_relay_to_channel since we want to check
4666 whether we have anybody channel before encrypting anything.
4667 Affected files silcd/packet_[receive/send].c.
4669 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Fixed the [AdminConnection] server config section to support
4672 multiple entries. Affected file silcd/serverconfig.c.
4674 * Added support into the server to check the validity of the
4675 incoming connection before executing any KE or authentication
4678 * The connection configuration is now saved to the KE and
4679 connection auth protocol contexts and not fetched anymore in
4680 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4682 * The local hosts listenning address and port is also resolved
4683 now when starting the server. We want to have the socket object
4684 to include the real address and port for the listener. Added
4685 new function silc_net_check_local_by_sock into the files
4686 lib/silcutil/silcnet.[ch].
4688 * Fixed a broadcast bug in server -> do not broadcast if we
4691 * Fixed a routing bug. Do not route broadcast packets ever.
4692 Broadcast packets must be processed always and not routed since
4693 they may be destined to some other host than yourself and thus
4694 would get routed without no good reason. Affected file is
4697 * Added function silc_server_config_is_primary_route to check
4698 whether primary router connection has been configured (a router
4699 configuration that we are initiating). If there is not, we
4700 will assume that there is only two routers in the SILC network
4701 and we will use the incoming router connection as our primary
4702 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4704 * Changed the order of the broadcasting. Broadcast _after_ the
4705 packet has been processed not before. Affected file is
4708 * Fixed a [ClientConnection] parsing bug. The port was never
4709 parsed correctly thus resulting to port 0. Affected file
4710 silcd/serverconfig.c.
4712 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4713 argument and did not set the broadcast packet flag. Affected
4714 file silcd/packet_send.c. Fixed same bug in the function
4715 silc_server_send_notify as well.
4717 * If we receive NEW_ID packet for our own ID in the server, ignore
4720 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Removed the nickname from the Private Message Payload.
4725 Updated the code and the protocol specs.
4727 * Updated protocol specs for submitting to the IETF.
4729 * Tweaked the Random Number Generator a bit. Affected file
4730 lib/silccrypt/silcrng.c. Exported a new function
4731 silc_rng_[global]_add_noise which can be used to add more
4734 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Do not parse packets with different timeout when protocol
4737 is active -> may cause problem with rekey. Affected file
4740 * When server receives signoff notify it must not create
4741 new channel key if the client is on any channels since the
4742 sender of the signoff notify will create it.
4744 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Added printing of error messages during SKE protocol from the
4747 failure packet sent by server during SKE. Affected file
4750 * Removed the client's failure_callback handling with timeout
4751 and handle it immediately when received.
4753 * The SKE library returned wrong type in SUCCESS and FAILURE
4754 packets. They must be 32 bit MSB not 16 bit MSB.
4756 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Ok, rewrote the logic of the re-key and now it seems to work.
4759 I tested it on high traffic with frequent re-keys without
4760 problems. Added hmac_receive (and renamed hmac to hmac_send)
4761 in SilcClientConnection in lib/silcclient/client.h and
4762 in SilcIDListData in silcd/idlist.h. Also, removed the
4763 SilcPacketParserContext's cipher and hmac fields as they are
4764 not needed anymore and actually caused some problems when
4765 the ciphers and hmac's changed underneath the packet parser.
4767 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * If re-key protocol is active then process the incoming packets
4770 synchronously since we must assure that icoming packets encrypted
4771 with the old key is processed before the new keys is set to
4772 use. This is true other packets than for REKEY packets.
4773 Affected file silcd/server.c. The same was done to client library
4774 as well, affected file lib/silcclient/client.c.
4776 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Fixed bug in client and server to accept the force send if
4779 the packet is send from silc_[server/client]_packet_process
4780 function. Otherwise the packets are never delivered, oops.
4782 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Disable force sending of packets when REKEY protocol is active.
4785 We must assure that no packet is sent directly when rekey is
4786 performed. All packets must be sent through packet queue.
4787 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4788 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4789 function is silc_[server/client]_packet_send_real to check
4792 * Replaced the SIM paths from example config files to
4793 /usr/local/modules. Also, make install creates now
4794 /usr/local/silc/logs directory to hold all the SILC server
4797 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Made the configure.in.pre work on Solaris. Patch by salo.
4801 * Made all ciphers compatible with non-x86 machines. Defined
4802 CBC mode macros into lib/silccrypt/ciphers_def.h.
4804 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Fixed the make install.
4808 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * When MAC computation fails the silc_packet_decrypt returned 0
4811 even though it was supposed to return -1. Fixed this. The
4812 affected file is lib/silccore/silcpacket.c.
4814 * Do not replace the config files in /etc/silc (in make install)
4815 if they already exist. Affected file ./Makefile.am.
4817 * Do not send re-key packets immediately but through packet queue.
4818 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4820 * Changed silc_net_check_host_by_sock to return FALSE if the
4821 IP/DNS could not be resolved. Though, it returns the IP address
4822 now even if it could not resolve it (but returns also FALSE).
4823 Affected file lib/silcutil/silcnet.[ch].
4825 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Added silc_pkcs_decode_identifier to decode the public key's
4828 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4829 Added also silc_pkcs_free_identifier. Added also new context
4830 SilcPublicKeyIdentifier.
4832 * Added -S option to the silc client. It is used to dump the
4833 contents of the specified public key file.
4835 * Changed the PKCS api to return the public key length when
4836 setting the public key.
4838 * Fixed a fatal bug in the public and private key file loading.
4839 Affected file lib/silccrypt/silcpkcs.c.
4841 * Execute the packet parsing for client with zero (0) timeout
4842 if the protocol is active. Affected file silcd/server.c.
4844 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Made the key generation options to the silcd program. Added
4847 -C option, equivalent to client's option.
4849 * Added new [ServerKeys] config section to the server. It
4850 configures the server's public and private key.
4852 * Defined generic Public Key Payload into the protocol
4853 specification to send specific type of public keys and
4856 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4857 public key or certificate.
4859 * Implemented the GETKEY command to the server and to the
4860 client library and on user interface.
4862 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Made preliminary `make install' work.
4866 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Added SilcServerRekey context into silcd/idlist.h.
4870 * Added the PFS support as defined in the specification to the
4871 SKE protocol. Affected files lib/silcske/*.c.
4873 * Added `ske_group' field to the SilcServerRekey context to hold
4874 the number of the SKE group that is used with PFS in re-key.
4875 Affected file silcd/idlist.h.
4877 * Added PFS re-key support to the server. Affected file is
4880 * Added silc_protocol_cancel to cancel execution of the next
4881 state of the protocol. Affected file is
4882 lib/silccore/silcprotocol.[ch].
4884 * Added the re-key support with and without PFS to the client
4885 library. Re-key is performed once in an hour, by default.
4887 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4888 Added silc_client_rekey_callback and silc_client_rekey_final.
4889 Affected files are lib/silcclient/protocol.[ch] and
4890 lib/silcclient/client.[ch].
4892 * Removed the `hmac_key' and `hmac_key_len' fields from the
4893 SilcClientConnection structure; not needed. Affected file is
4894 lib/silcclient/client.h.
4898 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Do not ask whether user wants to use the negotiated private key
4901 for private messages, just use it. Affected file is
4902 silc/local_command.c.
4904 * Added `send_enc_key' and `enc_key_len' fields to the
4905 SilcIDListData structure since they are needed in the re-key
4906 phase. Affected file is silcd/idlist.[ch].
4908 * Implemented the simple re-key protocol into the server.
4909 Affected files silcd/server.c and silcd/protocol.[ch]. The
4910 re-key will be performed once in an hour, by default.
4912 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4913 Added silc_server_rekey, silc_server_rekey_callback and
4914 silc_server_rekey_final.
4916 * Removed Tunneled flag from the protocol. Updated the code
4917 and the specifications.
4919 * Adde `pfs' field to the SilcIDListData to indicate whether
4920 the PFS is to be performed in the re-key. Affected file is
4923 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4926 int64 of at least the xintXX size. If void * is less that 4
4927 bytes uint32 * will be used. Defined bool as boolean.
4929 * Changed _ALL_ unsigned long and unsigned int to uint32,
4930 unsgined short to uint16 in the source tree.
4932 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4933 not handle clients that has entry->data.registered == FALSE.
4934 They are not in the network anymore. Affected file is
4937 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Implemented the sending of the SERVER_SIGNOFF notify in the
4940 server. Affected file is silcd/server.c.
4942 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4943 Added also silc_notify_payload_encode_args into the
4944 lib/silccore/silcnotify.[ch].
4946 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4947 Affected file silcd/packet_receive.c.
4949 * Implemented the SERVER_SIGNOFF notify handling in the client
4950 library. Affected file lib/silcclient/client_notify.c. Also,
4951 implemnted the printing of the SERVER_SIGNOFF info to the
4952 application. Affected file silc/client_ops.c.
4954 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4955 if the deleting was successful. Affected file silcd/idlist.[ch].
4957 * Added support for public key authentication in the connection
4958 authentication protocol in the client library. Affected file
4959 lib/silcclient/protocol.c.
4961 * Changed the server's silc_idlist_get_clients_by_* interface
4962 to support already allocated array so that new entries may be
4963 added to pre-allocated array. Affected file silcd/idlist.[ch].
4964 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4965 and command replies.
4967 * All command reply functions in the server now calls the
4968 pending command callback even if error occured. This way the
4969 error will be delivered to the client as well. Affected files
4970 silcd/command.c and silcd/command_reply.c.
4972 * Fixed INFO command to return local server's info if no server
4973 was provided. Affected file lib/silcclient/command.c.
4975 * Removed RESTART command for good. Updated the code and the
4978 * Rewrote parts of the task system. It is a bit simpler now.
4979 Removed unsued task priorities. The affected files are
4980 lib/silcutil/silctask.[ch].
4982 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Moved the USERS printing from the library to the application.
4985 Affected files lib/silcclient/command.c and silc/client_ops.c.
4987 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Added channel key re-key support. The re-key is perfomed
4992 only by the router and is done once in an hour. Added `rekey'
4993 field to the SilcChannelEntry in the server. Affected files
4994 silcd/server.c and silcd/idlist.h.
4996 * Added silc_task_unregister_by_context into the file
4997 lib/silcutil/silctask.[ch].
4999 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added SILC_UMODE_GONE mode to indicate when the client is not
5002 present in the SILC network. Added also support to the local
5003 command AWAY that will set this mode. Added support of showing
5004 "xxx is gone" in WHOIS command. The USERS command shows the
5005 gone status as well.
5007 * Fixed setting server and router operator privileges in the
5008 server's UMODE command. Affected file silcd/command.c.
5010 * Merged the SKE KE1 and KE2 payloads into one payload. The
5011 new KE payload is equivalent to the old KE2 payload.
5013 Cleaned up the SKE Start Payload parsing. It now uses the
5014 simple buffer unformatting to do the parsing. A lot faster
5017 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5018 to the SKE that is used to indicate whether both of the SKE
5019 parties should perform authentication. By default only the
5020 responder performs authentication. By setting this flag also
5021 the initiator must do authentication. By default it is unset
5022 since in normal SKE case, client to server connection, only
5023 the responder should do authentication. When doing SKE between
5024 two clients both should perform authentication. Updated the
5025 code and the protocol specs.
5027 * A little fix to IDENTIFY command in the server. Search the
5028 client first by hash not nickname. Affected file is
5031 * Fixed the silc_client_close_connection to support closing
5032 the client to client connections wihtout deleting too much
5033 data. Affected file lib/silcclient/client.c.
5035 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5036 are received if protocol used to be active but is not anymore
5037 the application would crash due to NULL pointer dereference.
5038 Affected files silcd/server.c and lib/silcclient/client.c.
5040 * Added `hash' field to the SilcClientConnection to include
5041 the hash function negotiated in the SKE protocol.
5043 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5044 to set the channel founder authentication data. A client can
5045 claim the founder rights later by providing the authentication
5046 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5047 This way the channel founder can regain the channel founder
5048 privileges even it is left the channel. This works only on
5049 local server and the client must be connected to the same
5050 server to be able to regain the founder rights. Updated the
5051 protocol specs accordingly.
5053 Added support to the CMODE command in the client to set the
5054 founder auth data. Read the README to see how to set it.
5056 Added support to the CUMODE command to claim the founder
5057 rights. Read the README to see how to do it.
5059 Added support for the founder authentication to the Channel
5060 Entry in the server. Affected file silcd/idlist.h.
5062 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5063 server's CMODE command. Affected file silcd/command.c.
5065 * Added the following new functions into lib/silccore/silcauth.[ch]:
5066 silc_auth_get_method and silc_auth_get_data.
5068 * The server now saves the remote hosts public key to the
5069 SilcIDListData pointer. Affected file silcd/protocol.c.
5071 * The normal server now does not remove the channel entry from
5072 the cache if the founder authentication data is set. It used
5073 to remove it if the founder was the last one on the channel on
5074 the server and left the channel. The auth data is saved and
5075 if the channel is re-joined later the old entry is used with
5076 the old auth data. Affected files silcd/command_reply.c and
5079 * Removed the `pkcs' field from the SilcIDListData structure
5080 in the server; it is not used. Affected file silcd/idlist.h.
5082 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Fixed packet processing on slow links. Partial packets were
5085 never re-processed because the incoming data buffer was cleared
5086 by the application. Application must not directly clear the
5087 sock->inbuf, the packet processing routines handle it. Fixed
5088 this in client library and in server.
5090 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Fixed the WHOIS and IDENTIFY send reply function to really
5093 check whether to send list or just one entry. Affected file
5096 * Cleaned up the LEAVE command's channel key distribution. The
5097 affected file silcd/command.c.
5099 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5100 can enforce the channel mode as well. In that case the ID
5101 includes the ID of the server. The code now enforces the
5102 mode change if the router have different mode than the server.
5104 * The notify client operation with CMODE_CHANGE notify can now
5105 return NULL client_entry pointer if the CMODE was not changed
5106 by client. Application must check for this.
5108 * Added <Server ID> argument to INFO command to support server
5109 info fetching by Server ID.
5111 * Added silc_server_announce_get_channel_users to get assembled
5112 packets of channel users of the specified channel. Affected
5113 file silcd/server.[ch].
5115 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5116 was freed underneath the ID Cache.
5118 * Re-announce clients when the server received CHANNEL_CHANGE
5119 notify from the router. Affected file silcd/packet_send.c.
5121 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5123 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5124 crashed since it did not handle the fact that there is no cipher
5125 called "3" and didn't check the error condition. Now fixed.
5127 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5128 flag. It can be used to send message requests.
5130 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Implemented the RESTART command in the client.
5134 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5135 notice type messages. Added notice printing to the user
5138 * The channel keys are not re-generated if the channel's mode
5139 is PRIVKEY, ie private key on the channel exists. Affected
5140 files silcd/server.c and silcd/command.c.
5142 * Fixed a little bug in channel message delivery when channel
5143 private keys are set in the server. Affected file is
5144 silcd/packet_send.c.
5146 * Changed the setting on channel->on_channel = TRUE from the
5147 silc_client_save_channel_key to the JOIN command reply. The
5148 key payload is not received if the private channel key is set.
5149 Affected file lib/silcclient/command_reply.c and the
5150 lib/silcclient/client_channel.c.
5152 * When the CMODE_CHANGE notify is sent and the channel private
5153 key mode is removed the channel key must be re-generated in
5154 other cells as well. Added this support for the router in the
5155 silcd/packet_receive.c.
5157 * Added new local command NOTICE to send notice message on
5158 channel. Affected file silc/local_command.[ch].
5160 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Added new local command ME to the client. It is used to send
5163 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5164 some action. Affected file silc/local_command.[ch].
5166 * Changed channel_message and private_message client operations
5167 to deliver the message flags to the application. Added also
5168 the `flags' arguments to the silc_client_send_channel_message
5169 and silc_client_send_private_message functions. Affected file
5172 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Redefined the Private Message Payload to support private message
5175 keys and to support the new private message flags. Updated
5176 the protocol specs. Flags makes it possible to have for example
5177 CTCP style messages.
5179 * Added new type SilcPrivateMessagePayload and defined an API
5180 for it in the lib/silcclient/silcprivate.[ch].
5182 * Tested private message private keys successfully. Tested the
5183 private message key set, unset and list commands with the new
5186 * Redefined the Channel Message Payload to include the channel
5187 message flags (equal with private message flags) to support
5188 for example CTCP style messages.
5190 * Defined some of the message (for channel and private message)
5191 flags. Updated the protocol specs and added the flags to the
5192 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5194 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Added SilcKeyAgreementStatus type to the key agreement routines
5197 to indicate the current status and error if one occured.
5198 The status types are defined in the lib/silcclient/silcapi.h.
5200 * Added new local command KEY that is used to set and unset private
5201 keys for channels, set and unset private keys for private messages
5202 with remote clients and to send key agreement requests and
5203 negotiate the key agreement protocol with remote client. The
5204 key agreement is supported only to negotiate private message keys,
5205 it currently cannot be used to negotiate private keys for channels,
5206 as it is not convenient for that purpose.
5208 * Fixed a minor pending callback setting bug in the function
5209 silc_client_get_client_by_id_resolve, now the function works.
5210 Affected file lib/silcclient/idlist.c.
5212 * Added function silc_net_get_local_port to get local bound
5213 port by socket. Added to lib/silcutil/silcnet.[ch].
5215 * Added `sockets' and `sockets_count' fields to the SilcClient
5216 object. They hold the sockets of the listenning sockets in
5217 the client. Listenning sockets may be for example the key
5218 agreement server. Affected file lib/silcclient/client.[ch].
5219 Added functions the silc_client_add_socket and the
5220 silc_client_del_socket. They are exported to the application
5223 * Added ~./silc/clientkeys to support other client's public keys.
5225 * Renamed verify_server_key client operation to verify_public_key
5226 and added one argument to indicate the type of the connection
5227 (server, client etc.).
5229 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Added silc_server_connection_auth_request to handle the
5232 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5233 silcd/packet_receive.[ch].
5235 * Added silc_server_send_connection_auth_request into the
5236 silcd/packet_send.c to send the connection auth request packet.
5238 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5241 * Fixed the public key authentication in responder side in the
5242 server. The `auth_data' pointer includes the SilcPublicKey
5243 not the path to the public key. Affected file silcd/protocol.c.
5245 * Implemented the public key authentication in the initiator side
5246 in the server. Affected file silcd/protocol.c.
5248 * Removed the [RedirectClient] config section from the server
5249 configuration. Is not needed and I don't want to implement it.
5251 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Cleaned up the CMODE command in the server. It now works
5254 correctly and supports all the modes defined in the protocol.
5255 Affected file is silcd/command.c.
5257 * Added `hmac_name' field to the SilcChannelEntry in the server
5258 to hold the default HMAC of the channel. It can be set when
5259 creating the channel (with JOIN command). Affected files
5262 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5263 type to indicate the change of the current cipher and hmac
5264 on the channel. Client can safely ignore the <cipher> argument
5265 (if it chooses to do so) since the CHANNEL_KEY packet will
5266 force the channel key change anyway. The <hmac> argument is
5267 important since the client is responsible of setting the new
5268 HMAC and the hmac key into use.
5270 * Fixed the CMODE command in the client library as well.
5272 * Tested CMODE command in router environment successfully.
5274 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Show the version of the remote client (or server) when connecting
5277 to the server. It is logged to the log file. Affected file
5278 is silcd/protocol.c.
5280 * Fixed the KILLED notify handling in the client library. The
5281 client must be removed from all channels when receiving the
5284 Also, do not remove the client entry when giving the KILL
5285 command but when the KILLED notify is received.
5287 * Removed silc_idlist_find_client_by_nickname from the server.
5288 Not needed anymore. Affected files silcd/idlist.[ch].
5290 * Implemented the CHANNEL_CHANGE notify type handling to the
5291 server. Affected file silcd/server.c.
5295 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5298 notify between routers.
5300 * Implemented the INVITE command correctly to the server.
5302 * Implemented the INVITE notify type handling in the server.
5304 * Implemented the INVITE command to the client library and on the
5307 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Added function silc_server_get_client_resolve to find the
5310 client entry by ID from all ID lists and then resolve it
5311 (using WHOIS) if it cannot be found. Affected file is
5314 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Implemented the BAN command to the client library.
5318 * The JOIN command in the server now checks the invite list
5321 * Changed the silc_command_reply_payload_encode_va and the
5322 silc_command_payload_encode_va to support that if argument is
5323 NULL it ignores and checks the next argument. Affected file
5324 lib/silccore/silccommand.c.
5326 * Added silc_server_send_notify_ban to send the BAN notify
5327 type between routers.
5329 * Chaned the silc_notify_payload_encode to support that if
5330 argument is NULL it ignores and checks the next argument.
5331 Affected file lib/silccore/silcnotify.c.
5333 * Tested ban lists in router environment successfully.
5335 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Implemented BAN command to the server, in silcd/command.[ch].
5339 * Removed the BAN and INVITE_LIST modes from the CMODE command
5342 * Added function silc_string_match to regex match two strings.
5343 Affected files lib/silcutil/silcutil.[ch].
5345 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * Redefined parts of the SilcChannelEntry in the server to support
5348 the new ban and invite lists.
5350 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Redefined the INVITE command. The same command can be used to
5353 invite individuals to the channel but also to manage the invite
5354 list of the channel (to add to and remove from the invite list).
5355 Updated the protocol specs.
5357 * Added new command SILC_COMMAND_BAN that can be used to manage
5358 the ban list of the channel. Updated the protocol specs.
5360 * Removed the channel modes: the SILC_CMODE_BAN and the
5361 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5362 in the CMODE command. The equivalent features are now available
5363 using INVITE and BAN commands. Updated the protocol specs.
5365 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5366 in the network about change in the current ban list. The notify
5367 type is not used by the client.
5369 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5370 support the invite lists.
5372 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added new function silc_string_regexify that converts string
5375 including wildcard characters into regex string that can
5376 be used by the GNU regex library. Added into the file
5377 lib/silcutil/silcutil.[ch].
5379 Added silc_string_regex_combine to combine to regex strings
5380 into one so that they can be used as one regex string by
5381 the GNU regex library. Added into the file
5382 lib/silcutil/silcutil.[ch].
5384 Added silc_string_regex_match to match two strings. It returns
5385 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5387 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Imported GNU regex to the soruce tree into lib/contrib.
5390 Fixed some compiler warning from the regex.c.
5392 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Fixed MOTD command in the server to work in router environment.
5396 * Fixed the MOTD command in the client library to support
5397 the server argument in the command.
5399 * Added `nickname_len' argument to the silc_idlist_add_client
5400 in the server, as the `nickname' argument may be binary data
5403 * Added silc_idlist_get_channels to return all channels from
5406 * Implemented LIST command to the server. Affected file is
5409 * Implemented the LIST command to the client library and on the
5412 * Added [<user count>] argument to the LIST command reply.
5413 With private channels the user count is not shown.
5415 * Updated TODO and README.
5417 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * The client entry's data.registered must be TRUE even with
5420 global client entry on global client list. The data.registered
5421 is used to check whether the client is anymore in the network,
5422 for example with WHOWAS command so it must be valid.
5424 * Fixed the WHOWAS command in the server. It now actually works
5425 in router environment. Added function into silcd/command_reply.c
5426 silc_server_command_reply_whowas_save.
5428 * Added silc_idlist_purge function to the silcd/idlist.c
5429 to periodically purge the ID Cache.
5431 * Fixed INFO command in the server. It works now in router
5432 environment. Added <server name> argument to the INFO command
5433 reply. Updated the protocol specs.
5435 * Fixed minor bug in silc_idcache_purge to not purge if the
5436 expire value is zero.
5438 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5439 they were buggy because of the WHOWAS information.
5441 * Fixed local command MSG to handle the async resolving of
5442 the remote client properly. It used to fail the first MSG.
5443 Affected file silc/local_command.c.
5445 * Added `data_len' field to SilcIDCache context.
5447 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Update TODO. Todo in commands in the server.
5451 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5454 used by routers as broadcast packet to inform other routers
5455 about the changed user mode.
5457 Implemented the notify handling in the server. Affected file is
5458 silcd/packet_receive.c. Added the function
5459 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5461 * Added new generic Channel Payload and deprecated the New Channel
5462 Payload. The New Channel Payload is now the generic Channel
5465 * Added new argument `mode' to the silc_server_send_new_channel
5466 as it is required in the Channel Payload now.
5468 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5469 and created a new and real SilChannelPayload to represent the
5470 new generic Channel Payload. Implemented the encode/decode
5471 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5473 * Added silc_server_get_client_channel_list to return the list
5474 of channels the client has joined for WHOIS command reply.
5475 Affected file silcd/server.[ch].
5477 * Implemented the channel list sending in the WHOIS command reply
5478 in server and in the client.
5480 Implemented the channel list displaying on the user interface
5481 as well. Affected file silc/client_ops.c.
5483 * Added silc_channel_payload_parse_list to parse list of Channel
5484 Payloads. It returns SilcDList list of SilcChannelPayloads.
5485 Client for example can use this function to parse the list of
5486 channels it receives in the WHOIS command reply. The caller
5487 must free the list by calling silc_channel_payload_list_free.
5488 Affected files lib/silccore/silcchannel.[ch].
5490 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Added one new argument <user mode> to the WHOIS command reply
5493 to return the mode of the user in SILC. Updated the protocol
5496 Implemented it to the server and client.
5498 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Fixed the mode printing on the user interface on joining.
5501 Affected file silc/client_ops.c.
5503 * Implemented the UMODE command and user modes in general to the
5504 client library and to the user interface.
5506 * Implemented the UMODE command to the server.
5508 * The server now sends UNKNOWN_COMMAND error status if client sends
5509 unknown command. Affected file silcd/command.c.
5511 * All server commands now handle the command identifier the right
5512 way when sending the command reply to the client. The client can
5513 use to identify the command replies with the identifier.
5515 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Added silc_server_get_client_route to resolve the route to
5518 the client indicated by the client ID. Affected file is
5521 * Added silc_server_relay_packet as general function to relay
5522 packet to arbitrary destination. This deprecates functions
5523 like _send_private_message_key, _relay_notify etc. Affected
5524 file is silcd/packet_send.[ch].
5526 Removed silc_server_send_key_agreement,
5527 silc_server_send_private_message_key and
5528 silc_server_packet_relay_notify functions from the file
5529 silcd/packet_send.[ch].
5533 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5534 server. Affected file silcd/packet_receive.[ch].
5536 * Implemented the KILL command to the client. Implemented the
5537 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5538 Affected files lib/silcclient/command[_reply].c and
5539 lib/silcclient/client_notify.c. Implemented the KILL notify
5540 printing in the user inteface.
5542 * Fixed a lot silc_parse_nick memory leaks from the client
5543 library in the file lib/silcclient/command.c.
5545 * Changed the silc_server_send_notify_on_channels's `sender'
5546 argument from SilcSocketConnection to SilcClientEntry to
5547 check the sender as entry and not as connection object and not
5548 to send to the client provided as argument. The affected file
5549 is silcd/packet_send.[ch].
5551 * The notify packets that are destined directly to the client used
5552 to not to be processed by the server. Now changed that and the
5553 server processes all notify packets. After relaying the packet
5554 to the client the notify packet is processed in the server.
5556 * The silc_server_free_client_data now checks whether there is
5557 pending outgoing traffic for the client and purges the data to
5558 the network before removing the client entry.
5560 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5563 an client is killed from the SILC Network. Updated the protocol
5566 Added new function silc_server_send_notify_killed to the
5567 silcd/packet_send.[ch].
5569 * Added function silc_server_packet_relay_notify to relay notify
5570 packets that are destined directly to a client. In this case
5571 the server does not process the notify packets but merely relays
5572 it to the client. Affected file silcd/packet_send.[ch].
5574 Added also silc_server_packet_process_relay_notify to check
5575 whereto relay the notify. Affected file is
5576 silcd/packet_receive.[ch].
5578 * Implemented the KILL command to the server.
5582 * Added the backup schema desgined last fall to the protocol
5583 specs for everyone to see. The specification is in the
5584 *-spec-xx.txt draft and the packet type definitions for the
5585 backup routers is in *-pp-xx.txt draft. Thusly, added also
5586 new packet type SILC_PACKET_CELL_ROUTERS.
5588 * A big security problem in the implementation discovered. The
5589 signoff of an client did not cause new channel key generation
5590 which it of course should've done. The channel keys must be
5591 always re-generated when client leaves (or signoffs) the channel.
5592 The silc_server_remove_from_channels funtion now handles
5593 the channel key re-generation.
5595 * Added `sender' argument to the silc_server_send_notify_on_channels
5596 to not to send the client provided as argument. Affected file
5597 silcd/packet_send.[ch].
5599 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Implemented OPER and SILCOPER commands into the server and
5604 * Added silc_auth_verify and silc_auth_verify_data to verify
5605 the authentication directly from the authentication payload.
5606 It supports verifying both passphrase and public key based
5607 authentication. Affected file lib/silccore/silcauth.[ch].
5609 * Added `hash' field to the SilcIDListData structure. It is the
5610 hash negotiated in the SKE protocol. Affected file is
5613 * Slight redesigning of the SilcAuthPayload handling routines.
5614 Do not send SilcPKCS but SilcPublicKey as argument.
5616 * Implemented the public key authentication support to the
5617 serverconfig. The public key is loaded from the provided path
5618 and saved as authentication data to void * pointer. Thus,
5619 changed the unsigned char *auth_data to void *auth_data;
5621 * Fixed SHUTDOWN command to send the reply before the server
5622 is shutdown. :) Affected file silcd/command.c.
5624 * Fixed fatal bug in CONNECT command. The hostname was invalid
5625 memory and server crashed. Affected file silcd/command.c.
5627 * Fixed fatal bug in CLOSE command. The server_entry became
5628 invalid but was referenced later in the command. Affected file
5631 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Fixed fatal bug in failure packet handling. Server ignored
5634 the failure and thus crashed when it came.
5638 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5641 that the command may be executed only once in (about) 2 seconds.
5642 The old SILC_CF_LAG flag is same but allows command bursts up
5643 to five before limiting.
5645 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5646 server code. Various commands now includes the CF_LAG_STRICT
5647 flag to disallow any kind of miss-use of the command.
5649 * Fixed the silc_buffer_unformat to not to allocate any data
5650 if the length of the data is zero. It used to allocate the
5651 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5653 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Changed the format of AdminConnection configuration section
5656 in the server. Added username of the admin to the format.
5657 Affected files silcd/serverconfig.[ch].
5659 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5660 to return admin configuration data by host, username and/or
5663 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Implemented WHOWAS command to the server. Added the functions:
5667 silc_server_command_whowas_parse,
5668 silc_server_command_whowas_send_reply,
5669 silc_server_command_whowas_from_client and
5670 silc_server_command_whowas_from_server
5672 * Added <Client ID> argument to the WHOWAS command reply. Updated
5673 the protocol specs accordingly.
5675 * Implemented WHOWAS command and command_reply to the client
5678 Implemented the WHOWAS printing on the user interface.
5680 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Added new argument to the WHOWAS command reply, the real name.
5683 It is an optional argument. Updated the protocol specs.
5685 * Added SilcIDCacheDestructor callback that is registered when
5686 the SilcIDCache is allocated. The callback is called when
5687 an cache entry in the ID Cache expires, or is purged from the
5688 cache. Added into lib/silccore/idcache.[ch].
5690 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5691 to destruct the client entries when the cache entry expires.
5692 Other ID Cache's in server and in the client library ignores
5695 * If the ID Cache entry's `expire' field is zero then the entry
5696 never expires. Added boolean `expire' argument to the
5697 silc_idcache_add function in the lib/silccore/idcache.[ch].
5698 If it is TRUE the default expiry value is used.
5700 * Added silc_server_free_client_data_timeout that is registered
5701 when client disconnects. By default for 5 minutes we preserve
5702 the client entry for history - for WHOWAS command.
5704 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Added support to the server to enforce that commands are not
5707 executed more than once in 2 seconds. If server receives
5708 commands from client more frequently, timeout is registered
5709 to process the commands. Affected file silcd/command.c.
5710 Added new function silc_server_command_process_timeout.
5712 * Changed NICK_NOTIFY handling in client library to check that
5713 if the client's nickname was changed, so there is no need to
5714 resolve anything from the server.
5716 * Removed error printing from the WHOIS and IDENTIFY commands.
5717 If error occurs then it is ignored silently in the client library.
5718 The application, however, may map the received error to
5719 human readable error string. The application currently maps
5720 the NO_SUCH_NICKNAME error to string.
5722 * Made the command status message public to the application. Moved
5723 them from lib/silcclient/command_reply.c to
5724 lib/silcclient/command_reply.h. The application can map the
5725 received command status to the string with the
5726 silc_client_command_status_message function.
5728 * Added check to the server to check that client's ID is same
5729 as the Source ID in the packet the client sent. They must
5732 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Added dist-bzip hook to the Makefile.am to make bzip2
5735 compressed distributions.
5737 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Server now enforces the maximum length for the nickname and
5740 the channel as protocol specification dictates. 128 bytes for
5741 nickname and 256 bytes for channel name.
5743 * Moved the WHOIS printing to the application. The client libary
5744 does not print out the WHOIS information anymore, the application
5745 must do it. Renamed silc_client_command_reply_whois_print to
5746 the silc_client_command_reply_whois_save.
5748 The client's idle time is also sent to the application now, and
5749 the idle is shown on screen.
5751 * Added silc_client_command_reply_identify_save to save the
5752 received IDENTIFY entries.
5754 * Do not check for channel private keys in message sending and
5755 reception if the channel does not have the PRIVKEY mode set.
5756 Affected file lib/silclient/client_channel.c.
5758 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5761 just surfaced after chaning the JOIN procedure.
5763 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Added silc_client_get_clients_by_list to get client entries
5766 from Client ID list, that is returned for example by JOIN
5767 and USERS command replies. The application should use this
5768 function for example when JOIN command reply is received to
5769 resolve the clients already on the channel (library does not
5770 do that anymore as USERS command reply is not used in the JOIN
5771 procedure anymore). Affected files lib/silcclient/silcapi.h and
5772 lib/silcclient/idlist.c.
5774 * JOIN command reply and USERS command reply returns now SilcBuffer
5775 pointers instead of unsigned char pointers when returning
5776 the client list and mode list.
5778 * Added <Client ID> argument to the JOIN command reply, mainly
5779 for the server to identify for which client the command was
5780 originally sent. Updated protocol specs accordingly.
5782 * Added SilcDlist private_key pointer to the SilcChannelEntry
5783 in the client to support the channel private keys. Affected
5784 file is lib/silcclient/idlist.h.
5786 * Added SilcChannelPrivateKey argument to the function
5787 silc_client_send_channel_message so that application can choose
5788 to use specific private ke if it wants to. If it is not provided,
5789 the normal channel key is used, unless private keys are set.
5790 In this case the first (key that was added first) is used
5791 as the encryption key.
5793 * Implemented the support for channel private key handling.
5794 Implemented the following functions:
5796 silc_client_add_channel_private_key,
5797 silc_client_del_channel_private_keys,
5798 silc_client_del_channel_private_key,
5799 silc_client_list_channel_private_keys and
5800 silc_client_free_channel_private_keys
5802 Affected file lib/silcclient/client_channel.c.
5804 * Added the support for the private keys in the channel message
5805 sending and encryption and in the message reception and
5806 decryption. Affected funtions are
5807 silc_client_send_channel_message and silc_client_channel_message.
5809 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Added SKE's key verify callback to the client library's
5812 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5814 * Removed the statement that server (or router) must send USERS
5815 command reply when joining to the channel so that the client
5816 knows who are on the channel. Instead, the client list and
5817 client's mode list is now sent in the JOIN command reply to the
5818 client who joined channel. This is better solution.
5820 * Added function silc_server_get_users_on_channel and function
5821 silc_server_save_users_on_channel to the silcd/server.[ch].
5823 * Removed function silc_server_command_send_users from the
5826 * Do not show topic on the client library anymore. The topic is
5827 sent in the command reply notify to the application and the
5828 application must show the topic now.
5830 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Added client searching by nickname hash into the IDENTIFY and
5833 WHOIS commands in the server as they were clearly missing from
5834 them. Affected file is silcd/command.c.
5836 * Fixed a bug in private message receiving in the client library.
5837 The remote ID was freed and it wasn't supposed, now it is
5840 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Minor fix to the channel payload; allocate the data area, as it
5843 needs to be of specific length.
5845 * If the key agreement port is zero then the operating
5846 system will define the bound port. Affected files are
5847 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5849 * Added new function silc_channel_payload_decrypt into the file
5850 lib/silccore/silcchannel.[ch].
5852 * Moved the channel message etc, check from silc_packet_decrypt
5853 to applications. The library calls now a generic
5854 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5855 when the packet is either normal or special. This was done to
5856 allow more wide range of checking that was not allowed when
5857 the code was in library. Now applications can do virtually any
5858 checks to the packet and return to the library the decision how
5859 the packet should be processed. Affected files are
5860 lib/silccore/silcpacket.[ch].
5862 Added silc_server_packet_decrypt_check to the server and
5863 silc_client_packet_decrypt_check to the client library.
5865 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5866 to send with specified source and destination information.
5868 * Channel message delivery between routers was broken after the
5869 channel key distribution was fixed earlier. The channel key
5870 was used be to distributed to other routers as well which is not
5871 allowed by the protocol. Now this is fixed and channel keys
5872 really are cell specific and the channel message delivery between
5873 routers comply with the protocol specification.
5875 * Fixed various commands in server to check also the global list
5876 for the channel entry and not just the local list. The affected
5877 file silcd/command.c.
5879 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Added assert()s to buffer formatting and unformatting routines
5882 to assert (if --enable-debug) when error occurs. Affected
5883 file: lib/silcutil/silcbuffmt.c.
5885 * Changed to auto-reconnect to check whether the remote host is
5886 router and register the re-connect timeout if it is. It used
5887 to check that whether we are normal server, but router must do
5888 auto-reconnect with another router as well. Affected file
5891 * Removed the [<key len>] option from CMODE command as the cipher
5892 name decides the key length, nowadays. See the defined ciphers
5893 from the protocol specification.
5895 * Added [<hmac>] option to the CMODE command to define the HMAC
5896 for the channel. Added SILC_CMODE_HMAC channel mode.
5898 * Added [<hmac>] option for the JOIN command so that user can
5899 select which HMAC is used to compute the MACs of the channel
5902 * Added Hmac field to the Channel Message Payload. The integrity
5903 of plaintext channel messages are now protected by computing
5904 MAC of the message and attaching the MAC to the payload. The
5905 MAC is encrypted. Now, it is clear that this causes some
5906 overhead to the size of the packet but rationale for this is that
5907 now the receiver can verify whether the channel message decrypted
5908 correctly and also when private keys are set for the channel the
5909 receiver can decrypt the packet with several keys and check from
5910 the MAC which key decrypted the message correctly.
5912 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5913 lib/silccrypt/silccipher.[ch].
5915 * Added silc_hash_len to return the digest length into the
5916 lib/silcrypt/silchash.[ch].
5918 * Rewrote parts of Silc Channel Payload interface in the
5919 lib/silccore/silcchannel.[ch]. The encode function now also
5920 encrypts the packet and parse function decrypts it.
5922 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Fixed a minor formatting bug in the SKE's key material processing.
5925 It actually might have processed the keys wrong way resulting
5928 * Redefined the mandatory HMAC algorithms and added new algorithms.
5929 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5930 and hmac-md5 truncated to 96 bits. The mandatory is now
5931 hmac-sha1-96. Rest are optional (including the one that used
5932 to be mandatory). Rationale for this is that the truncated HMAC
5933 length is sufficient from security point of view and can actually
5934 make the attack against the HMAC harder. Also, the truncated
5935 HMAC causes less overhead to the packets. See the RFC2104 for
5938 * Added new [hmac] configuration section. The SKE used to use
5939 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5940 is of course wrong. The official names that must be proposed in
5941 the SKE are the ones defined in the protocol specification
5942 (hmac-sha1-96 for example). The user can configure any hmac
5943 using any hash function configured in the [hash] section. At
5944 least, the mandatory must be configured.
5946 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5948 * Added HMAC list to the SKE proposal list. It has now both
5949 hash algorithm list and HMAC list. This makes the protocol
5950 incompatible with previous versions. The SKE now seems to work
5951 the way it is supposed to work, for the first time actually.
5953 * Defined plain Hash algorithms to the protocol specification.
5956 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Implemented support for key agreement packets into the server.
5959 Added functions silc_server_key_agreement and
5960 silc_server_send_key_agreement. Other than these functions,
5961 server has nothing to do with this packet.
5963 * Added support for private message key packets into the server.
5964 Added functions silc_server_private_message_key and
5965 silc_server_send_private_message_key.
5969 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5970 called in the protocol's final callback instead in the END
5971 protocol state. This makes a little more sense and in the same
5972 time in client we can use the same protocol routines for normal
5973 key exchange and to key agreement packet handling as well.
5975 * Added to both client's and server's KE protocol context the
5976 SilcSKEKeyMaterial pointer to save the key material. We will
5977 bring the key material to the protocol's final callback by doing
5978 this. The final callback must free the key material.
5980 * Added SKE's packet_send callback into client's KE protocol
5981 context so that the caller can choose what packet sending function
5982 is used. This way we can use different packet sending when
5983 doing normal SKE when doing key agreement packet handling (in
5984 the key agreement packet handling we do not want to encrypt
5987 * Implemented the responder side of the key agreement routines
5988 in the client. The client can now bind to specified port and
5989 accept incoming key negotiation. The key material is passed
5990 to the application after the protocol is over.
5992 * Implemented the processing of incoming Key Agreement packet
5993 in the client. Added function silc_client_key_agreement to
5996 * Implemented the intiator side of the key agreement routines
5997 in the client. The client can now initiate key agreement with
5998 another remote client. The key material is passed to the
5999 application after the protocol is over.
6001 * Created client_keyagr.c to include all the key agreement
6004 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6005 SILC_TASK_CALLBACK except that it is not static.
6007 * Created client_notify.c and moved the Notify packet handling
6008 from the client.[ch] into that file.
6010 * Created client_prvmsg.c and moved all private message and
6011 private message key routines from the client.[ch] into that file.
6013 * Create client_channel.c and moved all channel message and
6014 channel private key routines from the client.[ch] into that file.
6016 * Changed silc_client_get_client_by_id_resolve to resolve with
6017 WHOIS command instead of IDENTIFY command, in the file
6018 lib/silclient/idlist.c.
6020 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Implemented the SKE's responder side to the Client library.
6024 * When FAILURE is received to the protocol do not trust it
6025 blindly. Register a timeout to wait whether the remote closes
6026 the connection as it should do it, only after that process the
6027 actual failure. This was changed to both client and server.
6029 * Added client_internal.h to include some of the structures
6030 there instead of client.h in lib/silcclient/.
6032 * Added function silc_task_unregister_by_callback to unregister
6033 timeouts by the callback function.
6035 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Some "Incomplete WHOIS info" errors has been appearing on the
6038 log files. Took away the entry->userinfo check from WHOIS
6039 reply sending. The entry->userinfo is now " " if client did not
6040 provide one. I thought this was fixed earlier but something
6041 is wrong still. Let's see if the error still appears.
6043 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Fixed a minor bug in the login when the channel key is
6046 re-generated in the server. It used to generate the key in
6047 wrong order and thus caused problems in the channel traffic.
6049 * Fixed a minor bug in channel key distsribution after
6050 KICK command. The key was not sent to the router even though
6053 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Added silc_ske_process_key_material_data as generic routine
6056 to process any key material as the SILC protocol dictates. The
6057 function is used by the actual SKE library but can be used by
6058 applications as well. This relates to the private message keys
6059 and the channel private keys since they must be processed the
6060 same way the normal SILC session keys. The protocol dictates
6061 this. Affected files: lib/silcske/silcske.[ch].
6063 Added also silc_ske_free_key_material to free the
6064 SilcSKEKeyMaterial structure.
6066 * Defined silc_cipher_set_key function to set the key for
6067 cipher without using the object's method function. The affected
6068 files: lib/silccrypt/silccipher.[ch].
6070 * Implemented silc silc_client_add_private_message_key,
6071 silc_client_add_private_message_key_ske,
6072 silc_client_del_private_message_key,
6073 silc_client_list_private_message_keys and
6074 silc_client_free_private_message_keys functions in the
6077 Added functions silc_client_send_private_message_key to send
6078 the Private Message Key payload and silc_client_private_message_key
6079 to handle incoming Private Message Key payload.
6081 * Added Cipher field to the Private Message Key payload to set
6082 the cipher to be used. If ignored, the default cipher defined
6083 in the SILC protocol (aes-256-cbc) is used.
6085 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Removed lib/silcclient/ops.h file.
6089 Redefined parts of the SILC Client Library API. Created new
6090 file silcapi.h that deprecates the ops.h file and defines the
6091 published Client Library API. Defined also private message key
6092 API and channel private key API into the file.
6094 This is the file that the application must include from the
6095 SILC Client Library. Other files need not be included by
6096 the application anymore.
6098 * Added new key_agreement client operation callback and also
6099 defined the Key Agreement library API for the application.
6101 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6104 is used by clients to request key negotiation between another
6105 client in the SILC network. If the negotiation is started it
6106 is performed using the SKE protocol. The result of the
6107 negotiation, the secret key material, can be used for example
6108 as private message key.
6110 Implemented the Key Agreement payload into the files
6111 lib/silccore/silauth.[ch].
6113 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Redefined ciphers for the SILC protocol. Added some new ciphers
6116 and defined the key lengths for the algorithms. Changed the
6117 code accordingly. The default key length is now 256 bits.
6119 * Fixed SKE key distribution function silc_ske_process_key_material
6120 when the key length is more than 128 bits. The default key
6121 length in SILC is now 256 bits.
6123 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6124 to indicate unsupported algorithm.
6126 * Renamed rijndael.c to aes.c and all functions as well.
6128 * Fixed a long standing channel key setting bug in client library.
6129 Weird that it has never surfaced before.
6131 * Fixed bug in channel deletion. If the entire channel is removed
6132 then it must also delete the references of the channel entry
6133 from the client's channel list as the client's channel entry and
6134 the channel's client entry share same memory.
6136 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Implemented CONNECT and SHUTDOWN commands in the client.
6140 * Implemented CLOSE command to the client.
6142 * Added the function silc_idlist_find_server_by_name into the
6143 files silcd/idlist.[ch].
6145 Added the function silc_idlist_find_server_by_conn into the
6146 files silcd/idlist.[ch].
6148 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * DIE command was renamed to SHUTDOWN. Updated the both code
6153 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6154 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6156 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6159 * Added function silc_server_create_connection function to create
6160 connection to remote router. My server implementation actually
6161 does not allow router to connect to normal server (it expects
6162 that normal server always initiates the connection to the router)
6163 so the CONNECT command is only good for connecting to another
6166 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6169 or some other client was kicked from the channel.
6171 Implemented the handling of the notify type to both client
6174 Implemented silc_server_send_notify_kicked to send the KICKED
6175 notify. It is used to send it to the server's primary router.
6177 * Implemented the KICK command into server and client.
6179 * Added `query' argument to the silc_idlist_get_client function
6180 to indicate whether to query the client from server or not if
6183 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6184 to indicate that the client is not channel founder.
6188 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Removed the rng context from SilcPacketContext structure and
6191 changed that the packet routine uses the Global RNG API.
6193 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Added support for quit message that client can "leave" on the
6196 channel when it quits the SILC. It is ditributed inside the
6197 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6199 Added silc_server_free_client_data that will take the
6200 signoff message as argument.
6202 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6204 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Updated parts of the protocol specification to keep it up
6209 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6212 payloads in one packet.
6214 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6215 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6216 use now the new List flag.
6218 * Also deprecated the following packet types: REPLACE_ID,
6219 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6221 * Added list support for Notify packet in server.
6223 * Added silc_server_send_notify_channel_change to send the
6224 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6225 the silc_server_send_replace_id.
6227 * Added silc_server_send_notify_nick_change to send the
6228 NICK_CHANGE notify type. Deprecates the function
6229 silc_server_send_replace_id.
6231 * Added silc_server_send_notify_join to send the JOIN notify type.
6232 Deprecates the function silc_server_send_new_channel_user.
6234 * Added silc_server_send_notify_leave to send LEAVE notify type.
6235 Deprecates the function silc_server_send_remove_channel_user.
6237 * Added silc_server_send_notify_cmode and
6238 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6239 types. Deprecates the silc_server_send_set_mode function.
6241 * Added SERVER_SIGNOFF notify type to indicate that server has
6242 quit. This means that all clients on the channel from that
6243 server will drop. This can be also used when netsplit happens.
6245 Deprecated REMOVE_ID packet type since it is not needed anymore
6248 Added silc_server_send_notify_server_signoff to send the
6249 SERVER_SIGNOFF notify type. Deprecates the function
6250 silc_server_send_remove_id.
6252 Added also silc_server_send_notify_signoff to send the
6253 SIGNOFF notify type.
6255 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6256 SILC protocol from this day on. Changed the protocol
6257 specification as well.
6259 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6260 notify type. It is used between routers to notify about
6261 topic changes on a channel.
6263 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6266 * Partly updated the protocol specification to comply with the
6267 changes now made. It is still though a bit outdated.
6269 * The JOIN notify type now takes one extra argument <Channel ID>.
6270 The packet used to be destined to the channel but now the
6271 JOIN type may be sent as list thus it is impossible to
6272 destine it to any specific channel. By adding this argument
6273 it is again possible.
6275 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Added CREDITS file. The CHANGES and CREDITS file will appear
6278 in the distribution as well.
6280 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6283 types in the server's silcd/packet_receive.c.
6285 * Implemented CMODE and CUMODE to work in router environment.
6287 * Fixed minor encoding and decoding buglet from the
6288 lib/silccore/silcmode.c.
6290 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6293 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6295 * Changed all SilcConfigServer* and silc_config_server* to
6296 SilcServerConfig* and silc_server_config*, respectively.
6299 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Associated the ID (client or server ID) to the Authentication
6302 Payload to avoid any possibility of forging. Updated the
6303 protocol specification and the code accordingly.
6305 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * The RSA key length is now save to the RsaKey context in the
6308 key generation process in lib/silccrypt/rsa.c. The key length
6309 is now used to figure out the maximum size of the block allowed
6310 to be encrypted/signed.
6312 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6313 is equivalent to the silc_mp_mp2bin but does not allocate any
6316 * Changed silc_mp_mp2bin API to take length argument. If it is
6317 non-zero then the buffer is allocated that large. If zero, then
6318 the size is approximated using silc_mp_sizeinbase, which however
6321 * Created Global RNG API which is global RNG that application can
6322 initialize. After initializing, any routine anywhere in the
6323 code (including library) can use RNG without allocating a new
6324 RNG object. This was done to allow this sort of use of the
6325 RNG in code that has no chance to allocate RNG object. All
6326 applications currently allocate this and many routines in the
6327 library use this. Affected file lib/silccrypt/silcrng.[ch].
6329 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6330 it to use the Global RNG API.
6332 * Defined Authentication Payload into protocol specification that
6333 is used during SILC session to authenticate entities. It is
6334 used for example by client to authenticate itself to the server
6335 to obtain server operator privileges.
6337 Implemented this payload into the lib/silccore/silcauth.[ch].
6338 Implemented also routines for public key based authentication
6339 as the new protocol specification dictates.
6341 Moved definitions of different authentication methods from
6342 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6344 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6345 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6346 silc_pkcs_verify_with_hash functions into the file
6347 lib/silccrypt/silcpkcs.[ch].
6349 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * The client entry's userinfo pointer must be always valid.
6352 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6353 will fail since it requires the userinfo. Now, the userinfo
6354 is allocated as "" if actual userinfo does not exist. Actually,
6355 it must exist and it is totally Ok to drop client connections
6356 that does not announce the userinfo. However, we will make
6357 this workaround for now.
6359 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6360 to return the remote port by socket.
6362 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6365 SILC_SERVER_PENDING_EXEC and added an new macro
6366 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6367 data or when error occurs while processing the pending command.
6369 Added new argument `destructor' into silc_server_command_pending
6370 and to the SilcServerCommandPending object. This destructor is
6371 now called after calling the pending callback or if error occurs
6372 immediately. If error occurs the actual pending callback won't
6373 be called at all - only the destructor. The destructor may be
6374 NULL if destructor is not needed.
6376 All this applies for client library code as well. Similar
6377 changes were made there as well for the pending commands.
6379 In the client, the application must now allocate the
6380 SilcClientCommandContext with the silc_client_command_alloc
6383 * Added reference counter to the SilcServerCommandContext. Added
6384 function silc_server_command_alloc and silc_server_command_dup
6387 Same type of functions added to the client library for the same
6390 * Removed the cmd_ident from IDListData away since it is now
6391 global for all connections. It is the command identifier used
6392 in command sending and with pending commands. The affected file
6395 * Added reference counter to the SilcSocketConnection objecet to
6396 indicate the usage count of the object. The object won't be
6397 freed untill the reference counter hits zero. Currently only
6398 server uses this, and client ignores it. The client must be
6399 set to use this too later. The affected files are
6400 lib/silccore/silcsockconn.[ch]. Added also the function
6401 silc_socket_dup to increase the reference counter.
6403 This was mainly added because it is possible that the socket
6404 is removed underneath of pending command or other async
6405 operation. Now it won't be free'd and proper DISCONNECTING
6406 flags, etc. can be set to avoid sending data to connection that
6407 is not valid anymore.
6409 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6410 the connection. After that it sets SILC_SET_DISCONNECTED.
6411 It is, however, possible that the socket data is not still freed.
6412 The silc_server_packet_process now checks that data is not
6413 read or written to connection that is DISCONNECTED. The socket
6414 get's freed when the reference counter hits zero.
6416 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Changed the client operation API: channel_message operation's
6419 `sender' is now the client entry of the sender, not the nickname
6420 and the `channel' is the channel entry, not the channel name.
6422 In the private_message operation the `sender' is now also the
6423 client entry of the sender not the nickname.
6425 Affected file is lib/silcclient/ops.h and all applications
6426 using the client operations.
6428 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Moved the calling of ops->connect() from connect_to_server_final
6431 into receive_new_id functin since that is the point when the
6432 client is actually allowed to send traffic to network. The
6433 affected file is lib/silcclient/client.c.
6435 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6438 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6439 (if needs broadcasting) instead of broadcasting the packets one
6440 by one which would make a burst in the network traffic.
6442 * Added `broadcast' argument to the functions in silcd/server.[ch]
6443 silc_server_create_new_channel[_with_id] to indicate whether
6444 to send New Channel packet to primary router.
6446 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Added new function into the silcd/server.[ch] files:
6449 silc_server_create_new_channel_with_id to create new channel with
6450 already existing Channel ID.
6452 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6453 lib/silccore/silcpacket.h. This packet is used t send list of
6454 Set Mode payloads inside one packet. Server uses this to set
6455 the modes for the channels and clients on those channels, that it
6456 announced to the router when it connected to it. The protocol
6457 specification has been updated accordingly.
6459 * The silc_server_new_channel did not handle the packet coming
6460 from normal server as it normally does not send that. However,
6461 when it announces its channels it does send it. Implemented
6462 the support for that.
6464 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6465 into the file lib/silccore/id.h.
6467 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Fixed memory leaks in the functions silc_idlist_del_client,
6470 silc_idlist_del_channel and silc_idlist_del_server in the file
6471 silcd/idlist.c. All of those leaked like a sieve.
6473 * Fixed some small memory leaks in the client's function
6474 silc_client_notify_by_server.
6476 * Added functions into silcd/server.c: silc_server_announce_clients,
6477 silc_server_announce_channels and silc_server_announce_server.
6478 These functions are used by normal and router server to announce
6479 to its primary router about clients, channels and servers (when
6480 router) that we own. This is done after we've connected to the
6483 These functions effectively implements the following packet types:
6484 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6485 and SILC_PACKET_NEW_ID_LIST.
6487 * Added new functions into the silcd/packet_receive.[ch]:
6488 silc_server_new_id_list, silc_server_new_channel_list and
6489 silc_server_new_channel_user_list to handle the incoming
6490 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6492 * Added support of changing Channel ID in the function
6493 silc_server_replace_id. If the server that announces a channel
6494 to the router already exists in the router (with same name but
6495 with different Channel ID), router is responsible to send
6496 Replace ID packet to the server and force the server to change
6497 the Channel ID to the one router has.
6499 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6500 client that the Channel ID has been changed by the router. The
6501 normal server sends this to the client. Client must start using
6502 the new Channel ID as the channel's ID.
6504 Implemented handling of this new type into lib/silcclient/client.c
6505 into the function silc_client_notify_by_server.
6507 * Added new function silc_idlist_replace_channel_id into the files
6508 silcd/idlist.[ch] to replace the Channel ID.
6510 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Call silc_server_command_identify_check always when processing
6513 the IDENTIFY command in silcd/command.c
6515 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6518 send keepalive packets. The packet can be sent by clients,
6519 servers and routers.
6521 Added function silc_socket_set_heartbeat into the file
6522 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6523 If not set, the heartbeat is not performed. The actual
6524 heartbeat is implemented in the low level socket connection
6525 library. However, application is responsible of actually
6528 Added silc_server_send_heartbeat to send the actual heartbeat
6529 packet into silcd/packet_send.[ch]. Server now performs
6530 keepalive with all connections.
6532 * Added silc_task_get_first function into lib/silcutil/silctask.c
6533 to return the timeout task with shortest timeout. There was a bug
6534 in task unregistration that caused problems. TODO has been
6535 updated to include that task system must be rewritten.
6537 * The client library will now resolve the client information when
6538 receiving JOIN notify from server for client that we know but
6539 have incomplete information.
6541 * Rewrote parts of silc_server_remove_from_channels and
6542 silc_server_remove_from_one_channel as they did not remove the
6543 channel in some circumstances even though they should've.
6545 * Encryption problem encountered in server:
6547 The LEAVE command used to send the Channel Key packet to the
6548 router immediately after generating it. However, the code
6549 had earlier sent Remove Channel user packet but not immediately,
6550 ie. it was put to queue. The order of packets in the router
6551 was that Channel Key packet was first and Remove Channel User
6552 packet was second, even though they were encrypted in the
6553 reverse order. For this reason, MAC check failed. Now, this
6554 is fixed by not sending the Channel Key packet immediately but
6555 putting it to queue. However, this is more fundamental problem:
6556 packets that are in queue should actually not be encrypted
6557 because packets that are sent immediately gets encrypted
6558 actually with wrong IV (and thus MAC check fails). So, packets
6559 that are in queue should be encrypted when they are sent to
6560 the wire and not when they put to the queue.
6562 However, the problem is that the current system has not been
6563 designed to work that way. Instead, the packet is encrypted
6564 as soon as possible and left to the queue. The queue is then
6565 just purged into wire. There won't be any fixes for this
6566 any time soon. So, the current semantic for packet sending
6569 o If you send packet to remote host and do not force the send
6570 (the packet will be in queue) then all subsequent packets to the
6571 same remote host must also be put to the queue. Only after the
6572 queue has been purged is it safe again to force the packet
6575 o If you send all packets immediately then it safe to send
6576 any of subsequent packets through the queue, however, after
6577 the first packet is put to queue then any subsequent packets
6578 must also be put to the queue.
6580 Follow these rules and everything works fine.
6582 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Added new function silc_server_remove_clients_by_server to
6585 remove all client entries from ID list when the server connection
6586 is lost. In this case it is also important to invalidate all
6587 client entires as they hold the invalid server entry. This
6588 fixes fatal bug when server has lost connection and will reconnect
6591 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Made some sanity checks to silc_server_daemonise like to check
6594 whether the requested user and group actually exists.
6596 * Added sanity check to SKE's silc_ske_responder_finish to check
6597 that the public and private key actually is valid.
6599 * Invalidate the client's nickname when receiving Replace ID
6600 packet and the Client ID is being replaced. This means that the
6601 server will query the nickname if someone needs it (client)
6604 * Sort the ID Cache in client library when the ID Cache data
6605 has changed (needs sorting).
6607 * Do not allow for SILC client to create several connections to
6608 several servers. The client does not support windows right now
6609 and generating multiple connections causes weird behaviour.
6611 Irssi-silc client does support windows and can handle several
6612 connections without problems, see: www.irssi.org and SILC plugin.
6614 * Fixed some places where client was added to the IDList. The
6615 rule of thumb is following (in order to get everything right):
6616 If the client is directly connected local client then the
6617 `connection' argument must be set and `router' argument must be
6618 NULL to silc_idlist_add_client function. If the client is not
6619 directly connected client then the `router' argument must
6620 bet set and the `connection' argument must be NULL to the
6621 silc_idlist_add_client function.
6623 * The funtion silc_server_packet_send_local_channel actually did
6624 not check whether the client was locally connected or not. It
6625 does that now. Fixed a bug related to LEAVE command.
6627 * Fixed Remove Channel User payload parsing bug in server's
6628 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6630 * The server's silc_server_save_channel_key now checks also the
6631 global ID list for the channel as it might not be in the local
6632 list. Fixed a bug related to LEAVE command.
6634 * Is this the end of the [<unknown>] buglet that has been lurking
6635 around for a long time? A little for loop fix in server's
6636 silc_server_command_whois_parse that is used by both IDENTIFY
6637 and WHOIS command. At least, this was a clear bug and a cause
6638 of one type of [<unknown>] buglet.
6640 * WHOIS and IDENTIFY commands call the function
6641 silc_server_command_[whois/identify]_check function even if
6642 we are not router server.
6644 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Added --with-gmp configuration option. If set the GMP
6647 is always compiled in the SILC source tree. If not set then
6648 it is checked whether the system has the GMP3 installed. If
6649 it has then the GMP won't be compiled (the system's headers
6650 and library is used), if it doesn't have it then the GMP is
6651 compiled in the SILC source tree.
6653 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Changed RSA private exponent generation to what PKCS #1
6656 suggests. We try to find the smallest possible d by doing
6657 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6658 not security fix but optimization.
6660 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Added new config entry [Identity] to fork the server and run
6663 it as specific user and group. A patch from Bostik.
6665 * Imported Dotconf configuration library into lib/dotconf.
6666 This will be used to create the SILC configuration files later.
6667 It will appear in the distsribution after this commit.
6669 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * A big code auditing weekend happening. Auditing code for
6672 obvious mistakes, bugs and errors. Also, removing any code
6675 Removed files for being obsolete:
6677 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6678 inline in the file lib/silcutil/silcbuffer.h)
6680 o lib/silcutil/silcbufutil.c (the header has inline versions)
6682 Changed code to fix possible error conditions:
6684 o The buffer formatting routines now check that the destination
6685 buffer really has enough space to add the data. This applies for
6686 both buffer formatting and unformatting
6687 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6688 unformatting was changed to accomodate following rules:
6689 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6690 sent to the function while XXX_*STRING will not allocate or copy
6691 the data into the buffer. Instead it sets the pointer from the
6692 buffer into the pointer sent as argument (XXX_*STRING used to
6693 require that the pointer must be allocated already). This change
6694 makes this whole thing a bit more consistent and more optimized
6695 (note that the data returned in the unformatting with XXX_*STRING
6696 must not be freed now). The routines return now -1 on error.
6698 o Tried to find all code that use buffer_format and buffer_unformat
6699 and added return value checking to prevent formatting and
6700 especially unformatting errors and possible subsequent fatal
6703 o Changed ske->x and ske->KEY to mallocated pointers in
6704 lib/silcske/silcske.h. Fixed possible data and memory leak.
6706 o Added return value checking to all *_parse* functions. Fixed
6707 many memory leaks as well.
6709 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6710 so that buffer overflows would not happen. All code now also
6711 checks the return value as it can fail.
6713 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Added reconnection support to server if the normal server looses
6716 its connection to the router (for example if router is rebooted).
6717 The server performs normal reconnection strategy implemented
6718 to the server. Affected file silcd/server.c.
6720 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6722 * Added new packet type SILC_PACKET_SET_MODE that is used to
6723 distribute the information about changed modes (for clients,
6724 channels and clients channel modes) to all routers in the
6725 network. Updated the protocol specification accordingly.
6727 Added functions into silcd/packet_send.c and
6728 silcd/packet_receive.c: silc_server_send_set_mode,
6729 silc_server_set_mode.
6731 Added new files silcmode.[ch] into lib/silccore that implements
6732 the encoding and decoding of Set Mode Payload. Added new type
6733 SilcSetModePayload. Moved the definitions of different modes
6734 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6736 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Oops, a little mistake in server's connection authentication
6739 protocol. The protocol is not ended with FAILURE but with
6740 SUCCESS if the authentication is Ok. :) Affected file is
6743 * Implemented NICK_CHANGE notify handling in server in the file
6744 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6745 the local clients on the channel. After the changing nickname
6746 in router environment snhould work and the [<unknown>] nickname
6747 should appear no more.
6749 The silc_server_replace_id function that receives the Replace ID
6750 payload now sends the NICK_CHANGE notify type also in the file
6751 silcd/packet_receive.c
6753 * Changed WHOIS and IDENTIFY command to support the maximum amount
6754 of arguments defined in protocol specs (3328 arguments). This
6755 fixed a bug that caused problems when there were more than three
6758 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * Added extra parameter, command identifier, to the
6761 silc_client_send_command so that explicit command identifier
6764 Changed that ID list routines uses specific command identifier
6765 when sending WHOIS/IDENTIFY requests to the server so that they
6766 can be identified when the reply comes back.
6768 Affected files lib/silcclient/command.[ch],
6769 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6771 * Added `sender' argument to silc_server_packet_send_to_channel
6772 to indicaet the sender who originally sent the packet to us
6773 that we are now re-sending. Ignored if NULL. Affected file
6774 silcd/packet_send.[ch].
6776 * Added some server statistics support in silcd/server_internal.h
6777 SilcServerStatistics structure and around the server code. Also
6778 send some nice statistics information when client is connecting
6781 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6783 * Fixed channel ID decoding in server's JOIN command reply in
6784 silcd/command_reply.c
6786 * Fixed braodcasting of replace ID payload to not to send it if
6787 we are standalone server in silcd/packet_receive.c.
6789 * Fixed all channel message sending routines to not to send
6790 packets to clients that has router set, since they are routed
6791 separately in the same function earlier. Affects file
6792 silcd/packet_send.c and all channel packet sending functions.
6794 * In USERS reply, res_argv[i] are not allocated, the table
6795 is allocated. Thus changed that free the table, not its
6798 * In server's whois_check and identify_check if the client is
6799 locally connected do not send any WHOIS commands - they are not
6802 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Fixed some minor bugs in client when sending WHOIS command. The
6805 arguments was in wrong order.
6807 * Removed statis function add_to_channel from server in
6808 silcd/command.c that was previously used with the joining but
6811 * Tested USERS command in router environment successfully with two
6812 routers, two servers and two clients.
6814 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6816 * Reorganized the USERS command and command reply in client library
6817 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6818 When the command is given by user we register a pending command
6819 callback that will reprocess the command after the reply has been
6820 received from the server. When reprocessing the packet we then
6821 display the information. Thus, the USERS information is displayed
6822 now in the command callback instead of in the command reply
6823 callback. The processing of the command is same as previously
6824 when server has sent the command reply in the JOINing process.
6826 * Added to USERS command in silcd/command_reply.c to join the client,
6827 we didn't use to know about, to the channel after we've created
6828 a client entry for it. Also, for clienet we did know already still
6829 check whether it is on the channel or not and add it if not.
6831 * Removed silc_server_command_join_notify as the function and its
6834 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Changed the client's pending command handling to the same as the
6837 server's pending command handling. It is also now possible to
6838 execute command reply functions from other command reply
6839 function as the function callbacks for commands and command
6840 replies are one and same. The pending commands are not static
6841 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6842 in client connection context. Thus, pending commands are server
6843 connection specific as it is convenient.
6845 Changed the function silc_client_command_pending and
6846 silc_client_command_pending_del and added new function
6847 silc_client_command_pending_check. Removed the
6848 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6851 * Added cmd_ident, current command identifier, to the client
6852 connection context in lib/silcclient/client.h to keep track on
6853 command identifiers used in command sending. Client's command reply
6854 function handling now supports the mandatory command identifiers.
6856 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6857 funtions in client to fully support pending command callbacks.
6859 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6860 as one of the arguments to the application in the command reply
6863 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6864 before first releasing SILC but came back. Now it is removed again
6865 and should come back nomore. The FORWARDED flag was used only
6866 by the JOINing procedure by forwarding the command packet to router.
6867 Now, the JOINing procedure has been changed to more generic (due
6868 to various router environment issues) and FORWARDED is not needed
6869 anymore for anything. The protocol specification is yet to be
6872 Now, removed silc_server_packet_forward from server and the flag
6873 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6875 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6877 * Renamed NAMES command to USERS command. The NAMES was named that
6878 due to historical reasons. Now it is renamed. Also, rewrote
6879 parts of the USERS command. The nickname list is not sent anymore
6880 by the server. Only Client ID and mode lists are sent in the USERS
6881 command. Changed this also to the protocol specification.
6883 The client now resolves the names and stuff after it receives
6884 the USERS list from the server when joining to the channel.
6886 * WHOIS and IDENTIFY commands has been changed to support multiple
6887 Client ID's per command. One can now search for multiple users
6888 in the network by sending only one WHOIS or IDENTIFY command.
6889 Changed the code and the protocol specifications.
6891 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6892 uses silc_server_command_whois_parse to parse the request. */
6894 * If normal server, do not parse the WHOIS and IDENTIFY requests
6895 before sending it to the router. Saves some time.
6897 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Fixed JOIN command on client library. Wrong number of arguments
6900 used to crash the client.
6902 * Added silc_server_channel_has_global function to check whether
6903 channel has global users or not.
6905 * Added silc_server_channel_has_local function to check whether channel
6906 has locally connected clients on the channel.
6908 * The silc_server_remove_from_one_channel now checks whether the
6909 channel has global users or not after given client was removed from
6910 the channel. It also checks whether the channel has local clients
6911 on the channel anymore. If it does not have then the channel entry
6912 is removed as it is not needed anymore.
6914 * The silc_server_notify now checks on JOIN notify whether the joining
6915 client is one of locally connected or global. If it is global then
6916 the channel has now global users on the channel and that is marked
6917 to the channel entry. Also, it now saves the global client to
6918 global list who is joining and JOINs it to the channel. This is
6919 for normal server, that is.
6921 Changed silc_server_send_notify_on_channel,
6922 silc_server_packet_relay_to_channel and
6923 silc_server_packet_send_to_channel check if we are normal server
6924 and client has router set (ie. global client) do not send the
6925 message to that client, as it is already routed to our router.
6927 * Implemented LEAVE notify type handling in silc_server_notify
6930 * Tested LEAVE command in router environment successfully. Tested
6931 with two routers, two servers and two clients.
6935 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6937 * Implemented SIGNOFF notify type handling in silc_server_notify
6940 * silc_server_remove_id now removes the client entry from all channels
6941 it has joined and thusly sends SIGNOFF notify type.
6943 * Rewrote the NAMES list generation in server by removing two excess
6944 loops. The lists are created now inside one loop.
6946 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * silc_server_remove_channel_user checks now also global list
6949 for channel and client.
6951 * silc_server_new_channel_user checks now both local and global
6952 list for channel and client. Fixed a bug in client id decoding.
6953 Used to decode wrong buffer.
6955 * silc_server_channel_message checks now both local and global
6956 list for channel entry.
6958 * Tested channel joining (hence JOIN) in router environment
6959 successfully. Tested with two routers, two servers and two
6962 * Tested channel message sending in router environment successfully.
6964 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Added silc_server_save_channel_key into server.[ch] to save the
6967 received channel key in Channel Key payload processing. It is
6968 also used in JOIN command reply handling.
6970 Equivalent function silc_client_save_channel_key added into
6971 client.[ch] into client library.
6973 * Changed JOIN command reply to send information whether the channel
6974 was created or not (is existing already) and the channel key
6975 payload. Changed protocol specs accordingly.
6977 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6978 the request was sent by ID and not by nickname. Crashed on
6981 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6983 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6984 now correctly save the received data.
6986 * silc_server_free_sock_user_data now notifies routers in the
6987 network about entities leaving the network.
6989 At the same time implemented functions silc_server_remove_id
6990 and silc_server_send_remove_id to receive and send REMOVE_ID
6991 packets. The packet is used to notify routers in the network
6992 about leaving entities. The ID removed will become invalid in
6995 * Added function silc_idlist_del_server into server. Removes and
6996 free's server entry from ID list.
6998 * silc_server_private_message function now checks, if we are router,
6999 that the destination ID really is valid ID, naturally.
7001 * In router when NEW_ID packet is received (for new client) the
7002 hash of the Client ID is saved in the ID Cache but the
7003 client->nickname is set to NULL, instead of putting the hash
7006 IDENTIFY command now also checks that client->nickname must be
7007 valid. If it is not if will request the data from the server who
7008 owns the client. Added new function
7009 silc_server_command_identify_check.
7011 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7012 to set the command to already allocated Command Payload.
7014 * Tested private message sending in router environment with two
7015 routers, two servers and two clients. Fixed minor bugs and now
7018 * Fixed segfault from client's NAMES command. Used to crash if
7021 * Forwarded packets must not be routed even if it is not destined
7022 to the receiver. Changed server code comply with this.
7024 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * Added `require_reverse_mapping' boolean value to ServerParams
7027 structure. If TRUE (not default) the server will require that
7028 the connecting host has fully qualified domain name.
7030 If the reverse mapping is not required and hostname could not be
7031 found the IP address is used as hostname.
7033 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Implemented version string checking to both client and server.
7036 The check is incomplete currently due to the abnormal version
7037 strings used in development version of SILC.
7039 * Changed all command functions in server to use the new
7042 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Changed char *data to unsigned char *data in ID Cache system to
7045 support binary data as ID Cache data. Changed code to support
7046 binary data in lib/silccore/idcache.c.
7048 * Renamed silc_server_packet_relay_command_reply to
7049 silc_server_command_reply as it is normal packet receiving
7050 function. Rewrote the function to accept command replys for
7051 servers and not only for clients.
7053 * Mark remote router always as registered server if we are connecting
7054 to it. Otherwise, commands sent by the router to us are ignored.
7056 * All ID List find routines now returns the ID Cache Entry pointer
7057 as well if requested.
7059 * WHOIS command works now in router environment, tested with two
7060 routers, two servers and two clients.
7062 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7063 in router environment (as it is almost equivalent to WHOIS) but
7064 hasn't been tested thoroughly. Added new functions:
7066 silc_server_command_identify_parse
7067 silc_server_command_identify_send_reply
7068 silc_server_command_identify_from_client
7069 silc_server_command_identify_from_server
7071 * Disabled route cache adding because adding two different ID's with
7072 same IP replaces the old cache entry thus giving wrong route.
7073 The entry->router->connection is always the fastest route anyway
7074 so route cache may not be needed. Of course, new routes maybe
7075 established after receiving the ID when the entry->router->connection
7076 might not be anymore the most optimal.
7078 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Add route cache for received ID for fast routing.
7082 * Added silc_server_packet_route to route received packet on router
7083 that is not destined to us.
7085 * Renamed silc_server_get_route to silc_server_route_get.
7087 * Added id_string and id_string_len fields into SilcServer to
7088 include encoded ServerID for fast comparing without excess
7089 encoding of the ID's.
7091 * Cleaned up WHOIS command on server side. Added following static
7094 silc_server_command_whois_parse
7095 silc_server_command_whois_check
7096 silc_server_command_whois_send_reply
7097 silc_server_command_whois_from_client
7098 silc_server_command_whois_from_server
7100 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7101 arguments in command replies. All command functions should be
7102 updated to use this macro.
7104 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Minor typo fixes on command reply handling on server.
7108 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7110 * Added silc_server_command_add_to_channel internal routine to add
7111 the client to the channel after router has created the channel and
7112 sent command reply to the server.
7114 * Added generic silc_server_send_command to send any command from
7117 * Use static buffer with ID rendering instead of duplicating data.
7119 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Fixed a channel user mode bug when joining to a channel server gave
7122 everybody channel founder rights, oops.
7124 * We mark ourselves as the router of the incoming server connection
7125 if we are router ourselves. This way we can check in some packet
7126 sending functions whether it is locally connected server. For
7127 incoming router connections we put NULL.
7129 * For router sending packets locally means now always sending the
7130 packet cell wide; to local clients and local servers. For normal
7131 server sending packet locally means sending it to only local
7134 * Fixed the JOIN command to really work in router environment. If the
7135 channel is created it is always created by the router. Router is
7136 also responsible of making the initial joining to the channel,
7137 sending JOIN notify to the sending server and distributing
7138 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7139 does not exist server doesn't do anything else but forward the
7140 command to the router which performs everything.
7142 * Added silc_server_send_channel_key function to send the Channel Key
7145 * Added silc_server_create_channel_key to create new channel key. The
7146 channel key is now re-generated everytime someone joins or leaves
7147 a channel, as protocol dictates. Note: channel->key_len is the
7150 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7153 packet_receive.[ch] to separate packet sending and receiving
7154 routines. The server.[ch] now includes everything else including
7155 actual packet processing (writing and reading data) and other
7158 Renamed silc_server_private_message_send_internal to
7159 silc_server_send_private_message. The routine is still though
7160 used only to relay private messages as server does not send
7161 private messages itself.
7163 Renamed silc_server_new_channel to silc_server_create_new_channel
7164 and added new function sicl_server_new_channel that handles the
7165 incoming New Channel packet. Added also new sending function
7166 silc_server_send_new_channel to send New Channel Payload.
7168 * Added new function silc_server_notify to process incoming notify
7169 packet to the server/router. Server may then relay the notify
7170 to clients if needed.
7172 * Added new function silc_server_new_channel_user to process incoming
7173 New Channel User packet. Router will redistribute the packet and
7174 send JOIN notify to its local clients and locally connected servers
7175 if needed. Normal server will send JOIN notify to its local client
7176 on same channel when received this packet. Added also corresponding
7177 sending function silc_server_send_new_channel_user to sent the
7180 * Added boolean route argument to send_notif_to_channel and
7181 packet_send_to_channel functions to attempt to route the packet
7182 if it is TRUE and send only locally if it is FALSE.
7184 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7186 * silc_server_replace_id now broadcasts the received replace ID
7187 packet if it is not broadcast packet already. The router must
7188 broadcast to inform other routers about changed ID.
7190 * Added backpointer to server's router into SilcServer context in
7191 silcd/server_internal.h.
7193 * Fixed silc_server_packet_broadcast to send correct broadcast
7196 * The channel key is now distributed to the local client as soon
7197 as it is received from the router (in router environment) so that
7198 no other packet may be sent for the channel until client has
7201 * silc_server_remove_channel_user now broadcasts the received
7202 Remove Channel User packet if it is not broadcast packet already.
7203 The router must broadcast to inform other routers about removed
7206 * Added users field into SilcPacketContext that is a reference count
7207 of the context. One can increase the reference count by calling
7208 silc_packet_context_dup which is now changed to just increase the
7209 reference count instead of duplicating the data. The reference
7210 count is decresed by calling silc_packet_context_free that will
7211 free the data after the reference count hits zero.
7213 For now on the packet context and everything allocated into it
7214 (including the raw packet from network) must be freed by calling
7215 the new silc_packet_context_free function. Added also new function
7216 silc_packet_context_alloc that must be used now to allocate the
7217 context. This also means that if a routine is asynchronous from
7218 silc_[client/server]_packet_parse_type the packet context must
7219 be duplicated by calling silc_packet_context_dup. Otherwise it
7220 gets free'd after silc_[client/server]_packet_parse_type returns.
7221 Also, one must remember that if packet is duplicated then its
7222 reference count must be decresed by calling the free function as
7223 many times as it was duplicated.
7225 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7226 from both client and server.
7228 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Made joining to a channel working in router environment.
7232 * Cleaned up JOIN command on server side and create function
7233 silc_server_command_join_channel internal routine to make the
7236 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Changed silc_command_pending list to SilcDList. Also, added
7239 `ident' field to SilcServerCommandPending structure to identify
7240 the reply and to call correct callback.
7242 Added silc_server_command_pending_check function to replace the
7243 corresnponding macro. The silc_command_pending list is not
7246 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7247 to set identifier to previously allocated Command Payload. It
7248 is used to set identifier for command when resending Command
7251 * Added silc_command_payload_encode_payload to encode Command
7252 Payload buffer from SilcCommandPayload structure.
7254 * Added silc_argument_payload_encode_payload to encode Argument
7255 payload buffer from SilcArgumentPayload structure.
7257 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Changed WHOIS command to support router connection on server side.
7260 The whois request is always sent to router unless the server is
7261 standalone server. After server has received the reply from the
7262 router will it send the reply to the client.
7264 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7265 broadcast received broadcast packet. The function is used only
7266 by router. The broadcast packet is always sent to the router's
7269 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7270 render given ID to printable string, for log files for example.
7272 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * Made basic router to router connections working. At least they
7275 can now connect to each other but nothing really works the way
7276 they are supposed - yet.
7278 * Added new initiator token to RouterConnection configuration
7279 file in silcd/serverconfig.[ch]. It is used to tell whether we
7280 are the initiator to the remote router or whether we'll expect
7281 the other end to connect.
7283 * Moved registering of listener task to silc_server_init, hence
7284 the server starts listenning as soon as it is run, even if it
7285 does not have connections to other routers. Let's see how well
7288 * Changed default connection retry timeouts for more suitable in
7291 * Removed cipher and such arguments from silc_idlist_add_client
7292 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7293 Added new function silc_idlist_add_data to add the keys and stuff
7296 * Added SilcIDListData structure and added it to SilcClientEntry
7297 and SilcServerEntry as their first field in the structure. This
7298 way we can explicitly cast the ID entries to the SilcIDListData
7299 structure and get common data for the entries. In past, we had
7300 to first check what type of connection it is and then cast it to
7301 correct ID entry type. Now, we can directly cast the opaque
7302 pointer to the SilcIDListData (no matter what ID entry it actually
7303 is) and get the data needed.
7305 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7307 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7308 in some circumstances even if threre were timeout tasks, though not
7309 IO tasks, but tasks anyway. Now fixed.
7311 * Defined SilcServerConnection structure to hold connection specific
7312 stuff about directly connected servers and routers. The definition
7313 is currently in silcd/server_internal.h. I thought about having
7314 a bit more important role fro this struct but for now it is used
7315 only when connecting to other server (or router actually).
7317 * Added connecting retry support in server when connecting to
7318 router(s). The retry feature implement exponential backoff
7319 algorithm. Also, added SilcServerParams structure to hold default
7320 parameters for server. For now, it include these retry settings
7321 and are hard coded. After server is moded to be as Silc Server
7322 Library this structure will be more important.
7324 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Changed client librarys channel->clients table to SilcList and
7327 changed code accordingly.
7329 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Changed client's channel table to SilcList and changed code
7332 accordingly. Also changed SilcChannelClientEntry to include back-
7333 pointer to the channel so that client entry can use that structure
7334 as list as well and we have fast cross-reference to the channel.
7335 This change dramatically decreased the complexity of channel
7336 handling with client entry and vice versa (removed one extra
7337 loop when searching for channel entry from many functions).
7339 * Changed server->sim from table to SilcDList and changed code
7342 * NAMES command can now be used from user interface. It will show
7343 the user list on the channel, neatly.
7345 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7346 Code now saves realname of the user if it becomes available.
7348 * Renamed configure.in to configure.in.pre and made ./prepare
7349 script to automatically add correct version string to
7350 configure.in which it creates from configure.in.pre.
7352 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7354 * NAMES command reply now shows users mode with the nickname when
7357 * Moved silc_client_ch[u]mode[_char] functions from
7358 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7359 place sucks, they are utility functions and should be in some
7362 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7364 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7367 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * Added TRQ (efficient deque and list library) into lib/trq. This is
7372 a very good list library that is currently used in the SILC. Defined
7373 SilcList API over the library because I didn't like the API very
7374 much. See lib/trq/silclist.h for the API and examples of how to
7375 use the API. Fixed various places in the code to use the new
7376 SilcList API. The SilcList is meant for lists that has a structure
7377 already defined as a list. It is not suitable to add just some
7378 context to the list (in TRQ, the context is the list actually).
7380 So, I defined SilcDList that can be used for the purpose where
7381 predefined list structure does not exit. This can be used as
7382 such list. Now some context just can be added to the SilcDList.
7383 Currently this list is not used in the SILC just yet, though there
7384 are a lot places where this can replace dynamically allocated
7385 tables and I will fix these places, later, to use SilcDList.
7386 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7387 and use TRQ internally).
7389 Also fixed some annoying warning messages that the original TRQ
7390 code generated. Also minor changes to TRQ's Makefile.in.
7392 * Added support for querying by Client ID to both WHOIS and
7393 IDENTIFY commands into server, as required by the protocol.
7395 * Removed method function pointers from SilcBuffer structure. They
7396 weren't used to anything and just increased the context size for
7397 no good reason. This change also made silc_buffer_alloc and
7398 silc_buffer_free functions inline functions.
7400 * Disabled command flooding detection support until it's fixed so
7401 that it accepts commands in but does not execute them more than once
7404 * Added silc_net_localhost(), to return local hostname, into
7405 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7406 that must be initialized before calling silc_client_init.
7408 * Added new function: silc_server_send_notify_on_channels to send
7409 notify messages to all channels client has joined. It is assured
7410 that the message is sent only once per client.
7412 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7413 lib/silcutil/silcutil.[ch] as silc_format function. The new
7414 function is generic and is used by server as well, not only by
7415 the logging routines.
7417 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7418 the provided version string was not acceptable. Added new function:
7419 silc_ske_check_version into lib/silcske/silcske.h. The function
7420 must be implemented by the application (client or server) and it
7421 does not reside in the SKE library. The function checks the version
7422 string remote end sent.
7424 * Added back pointers (to opaque context and to SilcSocketConnection)
7425 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7427 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7428 duplicate packet context structure.
7430 * Changed `notify' client operation to send same arguments as client
7431 receives from server except for ID's. ID's are mapped to correct
7432 ID entry and that is returned. Also, if channel entry is not sent
7433 by server but the notify is for channel the channel entry is sent
7434 to application (otherwise application doesn't know that it is for
7435 channel (library gets it from packet's Destination ID)).
7437 * Added silc_client_remove_from_channels into client library to
7438 remove a client from all channels it has joined to. Used when
7439 received SIGNOFF notify from server. Added also new function
7440 silc_client_replace_from_channels to replace old ID entry with
7441 new ID entry on all channels. Used when received NICK_CHANGE
7444 * Fixed ID Cache list handling in silc_idlist_get_client in
7445 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7446 to get (or query) client by ID.
7448 * Updated TODO list.
7450 * Added connection authentication status message defined by the
7451 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7452 support for these into the code in client and server side.
7454 * Added generic function silc_client_send_command to send any command
7455 with variable argument list. Application should use this function
7456 to send commands if the command functions provided by the library
7457 does not suite for the application's user interface needs.
7459 * Added new `failure' client operation. Application is notified about
7460 received failure packet if client is executing a protocol. In this
7461 case the protocol's execution has failed.
7463 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7464 is required by the protocol.
7466 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7467 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7470 * Added status flag to SilcSKE object to indicate realtime status
7471 of the SKE protocol.
7473 * Application receives now exactly same command reply arguments as
7474 the library receives from server. However, if ID is received the
7475 corresponding ID entry is returned to the application (eg. Client
7476 ID is mapped to correct SilcClientEntry entry and that is returned).
7477 Changed command_reply client operation due to this change.
7479 * Changed all ID's in commands and in command replys as ID Payloads.
7480 Change affected both client and server side codes.
7482 All ID's sent in SILC network (with execption of ID's in SILC
7483 Packet header) are sent in ID Payload to support variable length
7486 * Server now notifies nick changes and notifies all clients on
7487 the channels about the new nickname (about the new Client ID,
7490 * Implemented CMODE command to change channel modes. Supports all
7491 channel modes defined by the protocol specs except ban and invite
7492 lists. (Also, private channel key mode is supported but support for
7493 setting private channel key in client is missing, thus, this mode
7494 has no effect on client side (except that server requires that the
7495 client uses private channel key and normal channel traffic does not
7498 Also, invite mode works per se, but INVITE command does not work
7499 yet correctly, so you can set channel as invite only channel but
7500 inviting clients to the channel does not work (it is yet to be
7501 thought what's the best way to do it).
7503 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7504 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7505 Implemented CUMODE command to change user's mode on the channel.
7506 Supports all modes defined by the protocol specs.
7508 * Added NAMES command reply to return users modes on the channel.
7510 * Removed unnecessary and slow ciphers from lib/silccrypt.
7512 * Set SO_KEEPALIVE option to connection sockets by default.
7514 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7516 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7517 redefined the Notify Payload into protocol specs.
7519 * Added silc_id_payload_parse_id to get ID directly from raw
7522 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7524 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7525 accept searching by Client ID as well.
7527 * Added support for LEAVE and SIGNOFF notify types in client library.
7529 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7530 to parse ID Payload from raw data.
7532 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Added flags parameter into silc_ske_assemble_security_properties
7535 function in lib/silcske/silcske.[ch].
7537 * Changed notify client operation to fit better for notify messages
7538 sent by server. The notify payload received from server is now
7539 passed to the application (after parsing it to SilcNotifyPayload).
7540 It is application's responsibility to retrieve the arguments
7541 from the payload and show the message the way it wants. The message
7542 sent by server is implementation specific.
7544 * Changed public keys to comply with the protocol specification.
7545 Old public keys are not supported anymore and are not compatible.
7547 * Removed nickname from Channel Payload as the latest draft removed
7548 it. The client must resolve the nickname from the NAMES command
7549 reply received when it joined the channel.
7551 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7553 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7555 * Fixed some errors in protocol specification drafts.
7557 * Created lib/silccore/silcnotify.c to implement Notify Payload
7558 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7559 generic payloads described by protocol specifications. The file
7560 includes implementations for ID Payload and Argument Payload.
7562 * Changed Command Payload implementation to use the new Argument
7563 Payload. Changed command_xxxx_payload to command_payload_xxxx
7564 to comply with SILC coding conventions.
7566 * Added suppport for Argument Payload handling in Notify Payload
7567 implementation as protocol requires it. Added the new support
7568 into server and client lib as well.
7570 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7572 * Added support for multiple nicknames on same channel. [n] is
7573 added locally to the nickname if there are more than one same
7574 nicknames on the channel.
7576 * Server now sends all nicknames that matched WHOIS request.
7577 Client also shows the list received from server.
7579 * Added TOPIC command to client side. User can now set and show
7580 current topic on channel.
7582 * Added MOTD command to client and server. Also, server sends the
7583 motd when client connects to the server.
7585 * Changed version strings to comply ISO 8601.
7587 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7589 * Fixed protocol error handling in client library. It should now
7590 cope even if the SKE fails for some reason.
7592 * Made new protocol specification drafts for submitting to IETF.
7594 * Implemented TOPIC command to server in silcd/command.c.
7596 * Added two new notify types into lib/silccore/silcnotify.h:
7597 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7598 notify nickname change and topic setting/change on a channel.
7600 * API change of command_reply operation in client library. The
7601 application gets now the status type received from server as well.
7603 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7605 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7607 * Cras fixed and optimized the packet handling even further and
7608 it should work now. Minor change to the prototype of function
7609 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7611 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * Added new function into lib/silcutil/silcschedule.[ch]:
7614 silc_schedule_with_fd to select() a specified fd. The function
7615 returns after timeout expires or data arrives or goes. The
7616 function is used by packet routines to wait that all data is
7617 received from network.
7619 * Fixed data reading from network in lib/silccore/silcpacket.c.
7620 The code now assures that all data is read from the fd and then
7621 continues packet processing. This was a bug fix since the code
7622 used to drop some data in some circumstances.
7624 * Added new function into lib/silcclient/client.[ch]:
7625 silc_client_start_key_exchange to start key exchange after
7626 connection has been established to server. The code internally
7627 now uses this funtion but its main purpose was to provide it
7628 for applications that perform their own connecting. After
7629 application has created a connection it merely calls this
7630 function to start the key exchange between client and server.
7631 The library takes care of everything else after that.
7633 Updated also lib/silcclient/README to explain the usage of
7636 * Do not send to application information that connection has
7637 been established. Application gets notified it by connect
7640 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Applied cras's patch to add silc_schedule_one function. The
7643 function runs scheduler once and returns.
7645 * Fixed the scheduler after cras messed it up. The timeout
7646 handling works now as it's supposed to work.
7648 * Added into lib/silccore/ silcnotify.h to include notify
7649 message types support. Changed silc_server_send_notify*
7650 functions, in server.[ch], to support those new notify types.
7651 Added the support for the notify types into client library,
7652 as well. Added new notify client operation into ops.h in
7655 * Changed silc_server_packet_send_to_channel to send normal
7656 packets instead of just channel message packets. The function
7657 is now used to send the notify packets to channels. It is not
7658 used to send channel message packets anymore, as server never
7661 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7662 va_arg()s as it seems to require it nowadays. I guess, if SILC
7663 is compiled with older va_arg() the new code should work anyway.
7665 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7667 * Splitted core library. Core library (lib/silccore) includes
7668 now only SILC protocol specific core (and common) components.
7669 Created new utility library (lib/silcutil) that includes more
7670 generic purpose stuff. The stuff for util library was taken
7671 from the old core library. This was minor and easy split.
7673 * Created SILC Client Library (lib/silcclient) that includes
7674 implementation of the SILC client without user interface. This
7675 was major move from silc/ directory. The code has been changed
7676 so that it is transparent towards the user interface. The
7677 silc/ directory includes now the same user interface as before
7678 and it uses the new client library. Read lib/silcclient/README.
7679 Basicly, the client library performs everything else related
7680 to SILC except user interface handling. Also, configuration
7681 files are considered to be part of user interface and library
7682 does not handle them.
7684 This change also changed a lot of structures, function naming etc.
7685 Most important change was that SilcClientWindow object was
7686 renamed to SilcClientConnection in the client library. Created
7687 also new file lib/silcclient/ops.h. Also added new files
7688 silc/local_command.[ch] and silc/client_ops.[ch].
7690 All these changes were made to make it easier for user interface
7691 designers to create what ever user interface for the SILC client
7694 It is also expected that the server will be moved to lib
7695 directory as well and SILC Server Library will be created;
7696 sometimes in the future.
7698 * Removed Local commands from lib/silccore/silccommand.h as
7699 they are application specific and new client library does not
7700 handle any of those anymore.
7702 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7703 old client implementation in silc/.
7705 * Added support for callback functions in SILC_LOG_* macros.
7706 Application can now set its own callbacks that will be called
7707 instead of using the default functions that will always print
7708 the debug messages to stderr (or stdout). Also, debugging can
7709 now be disabled by setting silc_debug to FALSE and re-enabled by
7710 setting it to TRUE. Note, that logging will still work even
7711 if debugging is disabled.
7713 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7714 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7715 silc_log_reset_debug_callbacks.
7717 * To enable debugging in silc client one must give now -d
7718 option on command line.
7720 * Changed silc_schedule_init to automatically allocate task queues
7721 if they are not allocated before calling it.
7723 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7725 * Added GMP 3.1 into math library.
7727 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7729 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7730 a channel in SILC network. The packet is used by servers and
7731 routers to notify other routers that user has left a channel.
7732 This little feature was missing until now. Added the feature
7733 to protocol specification as well.
7735 Added functions: silc_server_send_remove_channel_user and
7736 silc_server_remove_channel_user into server.[ch].
7738 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7739 lib/silccore/silcpacket.h. However, they are not implemented
7742 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Fixed joining to a channel and sending channel messages
7745 between server and router. The channel message sending should
7746 now work inside a cell.
7748 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Fixed the private message sending between server and router.
7751 The private message sending should now work inside a cell.
7753 * Added silc_server_replace_id into server.[ch] to replace
7754 existing ID in the SILC network.
7756 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7757 and silc_idlist_replace_server_id into idlist.[ch] in server.
7759 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7761 * Fixed the server to server connections. Server can again now
7762 connect to router. Router to router connections probably does
7765 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7767 * Added dynamic protocol registering support. Now protocols can
7768 registered and unregistered on the fly. Patch by cras.
7770 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * Added lib/contrib directory to hold routines that some platforms
7773 don't have but are needed by SILC.
7775 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7776 into lin/contrib to provide getopt() and getopt_long() for
7777 those who don't have it.
7779 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7781 * Added AWAY command to client. When away message is set and
7782 client receives a private message packet the client automatically
7783 replies to the sender with the away message.
7785 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7786 bug seemed to be the cause of recent problems when compiling
7789 * Added version detection support to SKE protocol specification
7790 and added the new changes to the SKE implementation as well.
7791 There were other minor changes in the SKE protocol as well.
7793 Many changes in lib/silcske/silcske.[ch] and in
7794 lib/silcske/payload.[ch].
7796 * Added ^U functionality, clear input line. Patch from cras.
7798 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7800 * Mainly small bugfixes on core library. Fixed some debugging
7801 logging and buffer overflow in silclog.c.
7803 * Updated config.sub and config.guess on the distribution tree.
7805 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7807 * Added command lagging support in server. Client may execute
7808 commands now only once in two seconds.
7810 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Optimized packet reception. MAC computation and checking is now
7813 also more optimized. A lot previously duplicated code is now
7814 used as generic by both client and server.
7816 * Fixed key pair generation in clientutil.c
7818 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7820 * Added into lib/silccore/silcbufutil.[ch] new function;
7821 silc_buffer_realloc.
7823 * Moved generic packet sending/encryption functions to
7824 lib/silccore/silcpacket.[ch] from client and server. Some
7825 rewriting of the functions.
7827 * Moved all generic packet reception/decryption functions to
7828 lib/silccore/silcpacket.[ch] from client and server. The
7829 packet processing is now much cleaner in both client and server.
7830 These were major changes in both client and server.
7832 * Created many common functions in server to do packet sending.
7833 Previously code were duplicated a lot, this has been removed
7836 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7838 * Rewrote major parts of the ID cache system. Don't know
7839 whether it is better now or not but at least the API is more
7842 * Major rewrite on ID cache stuff on client because of the ID
7843 cache API changes. Added idlist.c to client.
7845 * Also major rewrite on ID cache stuff on server as well.
7846 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7847 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7848 in hand, instead they are all put into the ID cache system now.
7849 All server_idlist_* routines uses ID cache now instead of
7850 traversing its own lists (those lists does not exist anymore).
7851 SilcIDList though still exists. Also, SilcXXXEntry's are
7854 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Finally made the SKE implementation compliant to the protocol
7857 specification. All mp integers are now binary encoded as
7858 opposed being HEX encoded.
7860 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7863 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7864 functions: silc_[encode/decode]_pem. Also added function
7865 silc_encode_pem_file to PEM encode with newlines ('\n') for
7868 * SILC public keys are now encoded either PEM or binary. Same
7869 option is for private keys as well. By default private keys
7870 are binary encoded and public keys PEM encoded. Silly HEX
7871 encoding were removed.
7873 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7874 function to create fingerprints.
7876 * Fixed a bug in SHA1; does not change the original data anymore.
7878 * Partly implemented INFO command on client and server side.
7879 Fixed CLEAR command. Changes to SERVER command; show current
7880 server(s) when giving command without arguments. Added
7881 VERSION command to client.
7883 * Added check to server that unregistered connections cannot
7884 execute commands (unless it is specificly allowed).
7886 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7888 * Fixed screen refresh.
7890 * Fixed channel joining bug from client. On some circumstances
7891 client tried to join to a channel it had already joined.
7893 * Added public key verification process into client's protocol.c.
7894 The client now verifies the public key from user and saves
7895 it into ~./silc/serverkeys/ directory.
7897 Added into: clientutil.[ch]: silc_client_verify_server_key.
7899 * Changed SKE protocol's silc_ske_initiator_finish function
7900 to accept callback function that verifies the received public
7901 key. Removed old silc_ske_verify_public_key function.
7903 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7905 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7906 silc_pkcs_private_key[_data]_set.
7908 * Made the password and public authentication more cleaner in
7909 server's protocol.c.
7911 * Removed historic and obsolete protocol `channel_auth' from
7912 both client and server.
7914 * Removed wrong way of sending command status messages from
7915 server to client in server's command.c. The old way violated
7916 protocol specification.
7918 Changes to silccore/silccommand.[ch]: removed
7919 silc_command_encode_status_payload -> not needed anymore,
7920 changed silc_command_encode_payload_va to accept extra
7921 argument on variable argument list. The argument type must
7922 now be provided to the function. Also, added new function:
7923 silc_command_encode_reply_payload_va which is same as
7924 normal command_encode_payload_va except command status type
7925 is provided as extra argument.
7927 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Added ~./silc directory handling. The directory includes the
7930 public and private keys for the client.
7932 Added silc_client_check_silc_dir, silc_client_create_identifier
7933 and silc_client_load_keys.
7935 * Implemented SILC protocol compliant public key. Added public
7936 and private key saving to and loading from files.
7938 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7939 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7940 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7941 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7942 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7944 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7945 silc_pkcs_load_[public/private]_key.
7947 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7949 * Added silc_server_get_route (route.[ch]) to get connection
7950 data for the fastest route for given ID.
7952 * Implemented INVITE command on client and server. The command
7953 were re-defined in the SILC Protocol Specification and the
7954 implementation now complies with the specification.
7956 * Implemented PING command on client and server.
7958 * Implemented NAMES command on client and server. The server side
7959 supports currently only normal server not router server yet.
7960 Some changes to NAMES definition in SILC protocol specification.
7962 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7964 * Implemented LEAVE command on client and server.
7966 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7967 again. This change was made to the protocol as well. Server
7968 should not violate the protocol specification anymore.
7970 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7972 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7973 was tested. SOCKS4 was not but should work anyway.
